There's so much hot garbage I found in those states when looking at the GRR (just one minor example). But if this is the sort of thing I can expect when reporting issues, it's not worth my while.
We appreciate reporting of any hot garbage - i.e. anything that is clearly and objectively "wrong" - so that it can be addressed.
That said, there are
established guidelines as to where waypoints are needed. It's perfectly fine to suggest that waypoints outside of these guidelines be added if there is some reasonable argument to be made in favor of doing so, but since their inclusion isn't explicitly required it's not unreasonable for such suggestions to see some discussion as to their merit.
Regarding the GRR intersection points specifically, I think it's perfectly reasonable to add them. Whether or not the GRR itself ultimately ends up being mapped, a user may still have use for them.
As for this counterargument to that...
The route sets in those states are among the oldest in the CHM/TM system. The team members maintaining those sets have done so from the beginning. If in all those years no GRR or other traveler needing those points has asked for their addition, ISTM their addition is a low priority.
I'm going to point out that just because no one has explicitly requested these points doesn't mean no one would benefit from their addition. Especially in the CHM days, it was well established that only contributors were entitled to make requests for specific points. Anyone else requesting one would usually have their request denied due to a desire to keep the number of points down on account of server resource constraints.
Hell, even as a contributor now, there are numerous places in my travels where I left a route (or turned around) at a location that isn't a waypoint and I typically just use the nearest one rather than bothering someone to add a point at an otherwise insignificant place just for my sake.
And this is to say nothing of the users who never come on to the forum at all and may not even be aware that requesting a point is a thing they can do.
We know that traveling the Great River Road is a thing some number of people have done and/or have plans to do, and without exhaustively surveying our userbase we can't assert that this doesn't matter to anyone.
...all that said, if the maintainers of the affected states have other things they'd rather prioritize over this (such as addressing the aforementioned hot garbage), that's also understandable.
