The data's hunky dory.

Well speaking personally:
1. I'm still trying to fully understand what you're proposing.
2. Wondering whether it really is a problem. (can't you work out the 
adjoining ways to ones that are tagged layer=*? They would have the same 
start or end point or intersect)
3. Could you not mitre the line ends?

4. On consideration I still thinks it's a failing in the rendering 
software & should be fixed by the renders. When I first joined in with 
OSM I asked why this & that hadn't been done. The reply was, yes it can 
be done, why don't you get on and do it; which I think was a reasonable 
response. OSM is a do-it-yourself, self contribution project.
To expect others to use their time instead of yours is a bit arrogant. 
I'm not convinced that the time spent splitting ways & adding news tags 
to them at *every* way with layer=* is economical.

Oh & also many are still asleep on the other side of the world.
