Junction style guide: ramp restriction inconsistency

For reference, two or three weekends ago I received a route which included taking the off-ramp-to-on-ramp route on a standard diamond interchange in an area I thought I had restricted long ago. Maybe I did, maybe not. I was the last editor, but since turn restriction changes don't update the segment last updated data, there's no way to know. All involved segments of freeway, ramps, and overpass were all the same city name. The wiki guide is still correct and the reasons why we do this are still valid.

With more Wazers and more accurate traffic data, Waze is likely getting "better" at not doing this routing, but the fact remains that the code still allows it, even with no traffic impact, and that only makes it more likely to be routed like this when traffic on the freeway is backed up. This ramp-to-ramp route is illegal in many states, just like using parking lots to bypass traffic on a surface street.

On the client, no instruction. In live map with routing script, it lists all the continues in the right side.

In cases where it is legal to go straight, wouldn't this cause Problem Reports whenever someone does go straight? While seemingly pointless to do so, I have no doubt it happens.

At the intersection that started the discussion, the signage in place explicitly lists that you can go straight.

Just an FYI for anyone following along. Discussion of routing off and back on via ramps has also popped up over here, referring to this interchange. For the record, the path via ramps is 1082 meters, via the freeway is 1100 meters.

Has the problem with shields only being displayed if the space is included been fixed?

Whether or not it is legal, I see a LOT of driver complaints about bad driving instructions and bad junctions when they get routed off the highway and then back on.
Especially when they followed the instructions, but even when they didn't.

I have tried adding a bunch of nodes along the ramps to 'try and stop the off/on routing' in some places in the middle of no where. In the case I am thinking of, I could NOT forbid the traffic because there was also an access road that went through the same intersections.

In any case, the added nodes did NOT stop the driver complaints. GPS tracks and routes still showed WAZE trying to route them off/on.

As I said earlier, I have seen URs posted in the middle of no where, in places that there would never be traffic jams.

Here is one where there were several URs complaining about being routed off/on.
intersection with nodes added to prevent 'off/on' routing.

I tried adding a bunch of nodes along the ramps.
I don't think it helped, but I don't see any URs there right now.

EDIT: I don't know what happened to the link. I thought I had put it there but just saw no link so put it now.

I don't see the conflict. My understanding is that conditions like the slow speed on the freeway is what causes off/on routing over ramps. Many consider this to be bad routing even if faster, thus the straight-through prohibition.
