If additional shaping is needed, then add points at minor roadways.
Why are these preferable to shaping points? Unused points at minor roadways are just clutter.
In the context of my comment, these points
are shaping points -- just visible ones.
Thus "Why are these preferable to hidden points?" would be a better question to ask.
All points, visible & hidden alike, are usable in .list files. If a point is needed for shaping in a general area anyway, why not make it a visible one, so travelers will have the ability to fine-tune their travels. If someone
has been to his cousin Bob's house nearby, he can use a minor
OakLn type point without having to go to GitHub and find out that +X123456 best represents his travels.
As far as clutter goes, the nature of how the lateral tolerance works naturally limits how dense points are going to get before a route is adequately shaped. IMO the results from shaping won't be
super bad, certainly better than a lot of those really short multiplexes that are out there.
Because you never know where somebody might have to U-Turn or there could be a detour in play due to a road closure.
Of course. Maybe you've noticed that when people do that, they submit point requests, and it in nearly every case, the collaborator complies. Little is gained by adding these points before they're needed.
It's useful to draw a distinction between when points are needed
by a user, after a system is in Preview, vs. when points are needed
for shaping, usually when a route is first drafted.
All that said, ISTM (not checking the HB) that these KY routes are implemented properly as-is WRT points, needed for shaping, included visibly.
