BUT: Even though the urban frontage roads in Texas, Oklahoma, and a few other states are major roads in and of themselves, worthy of being called primary street due to their heavy use, should they be considered as part of the "primary road" type selected for long-distance routing? Assuming that primary streets fall under "primary road"; at the meeting it seemed that Waze isn't quite sure they do.
If Primary Street is modified to be given higher priority than Street, I would hope that it is still less than the priority given to Minor Highway or above. But we don't know how granular their priorities can be.

Maybe not. Based on how the Service Roads are rendered on the Live Map (not at all except for name), I assume the original intent was to reduce clutter at certain zoom levels. No need to show these frontage roads since it follows the main road, so just show the main road to users until they would actually need the frontage road. But the client doesn't seem to hide them like the live map does.

Good example to look at. I could argue Private, Parking Lot, and Service Road if I tried
If we use Service Road, maybe restricting the right turn from the little segment to Oklahoma would be enough? Of course I am sure people would violate it and throw up errors and some well meaning person would enable the turn again. Sigh.
This is where my thought of more turn options would be nice - allowed, restricted, not preferred. We could then set the turns through that segment as not preferred.
Any chance average speeds would eventually make the shortcut less appetizing?
Also, here is an example where I agreed with your thinking on when a frontage road is NOT a Service Road: https://www.waze.com/editor/?zoom=4&lat ... 2,41768702
Woodhaven Rd (PA 63) is a limited access freeway with highly-traveled frontage roads in both directions. Their primary purpose are as connections to on & off ramps for the highway so I gave them the Primary Road designation.
And this fits into my "rule" that any ramp should terminate on at least a Primary Street as well. (Except for say rest areas or ramps to a private/secured campus.
