By default, all state highways are mH or higher. Some states which have both primary and secondary state highways may wish to demote the secondary state highways into the "State Hwy BUS, SPUR[a], LOOP" column. Some states don't have county routes at all; some states have "county highways" and "county roads" and may wish to make the former mH+ and the latter just Street+.
But the bulk of the guidance remains the same — nothing major changes in FC, except that some states might just use the "Other Freeway" class (as opposed to "Other Freeways and Expressways"), thereby placing all partially-limited-access 'expressways' into the "Other Principal Arterial" class. Michigan does this, for example. That doesn't actually change any FC rule, it simply makes the distinction easier for us in that state. Also, the guidance as to US highways remains the same.
So it isn't really necessary for all 50 states to supplement the FC guidance, as some will not need to change any of the state highway rules at all. If anything, making a state chart should only involve renaming some column headers to match that state's maps and maybe removing a column or row or two if they don't apply. For example, Michigan does not have "Other Expressway", and calls the next two classes "Other Principal Arterial" and "Minor Arterial"; Louisiana has "Freeways/Expressways" and "Principal Arterial" and "Minor Arterial", and "Parish Roads" (not county routes), no Interstate business routes, no CONN or ALT (I think) state highways, and so forth.

The goal of the automatic upgrade to MH minimum for US routes was to have a consistent "resolution" level, which is the pruning concept discussed elsewhere as part of the FC rollout. A US route collector (actually any collector) classified as a Primary Street segment will not be considered apart from the first or last 15km of a short route or 50km for a longer route. Major Highways do not have that limitation, and they help better reflect the "network" that makes up the US highway system. The upgrade to MH doesn't mean that Waze would prefer the collector portions of US-51 over another potentially faster road, but it would at least consider them for longer routes.
Unless as a collector it routes someone through a fire swamp or is filled with rodents of unusual size, it sounds like it may be a good bypass for I-55 if someone has "avoid highways" (freeways) enabled. Waze would be more willing to use it for longer distance travel or detours as a MH if it's deemed faster than any other route. Keeping it as PS may end up routing such a user way out of the way even if US-51 otherwise would be part of a fastest or shortest non-freeway route.
Perhaps we need to get a basic section on "pruning" added to the wiki as well. That may help clear up some confusion as to where road types actually do matter from a routing perspective.

On several occasions I have been routed off a congested interstate onto a nearby US Highway or other MH/mH and around some very gnarly traffic (accidents, construction, rubberneckers). These are routes that would previously not have been considered.
If I could be granted one wish, it would be that everyone prioritizes getting the US Highway system upgraded to at MH or FWY (as appropriate). Spending most of my time in the New England area I really took it for granted, but driving more of the southeast and midwest I have come to realize how useful it is.
Emergency Vehicle and DOT Service Roads Service road.png
Emergency.jpg "Emergency and Authorized Vehicles Only" and DOT Service Roads are to be treated as Non-drivable roads. These are found primarily through the median of divided highways to connect opposite direction lanes. If mapped, they should not be connected to any drivable road, with properties set to road type Private Road, and lock the segment at as high a rank as possible, up to rank 5.
