Quote from you:
"It's just painful to work with many small segments (to add or rename
tags or use route relations)"

I don't understand how the turning lanes plugin has anything to do with 
the basics tasks you describe. It should be relatively easy to have some 
form of "router" in editor to handle route relation building, it would 
help even with longer ways enormously (I think there might be some 
routing plugin for josm but I haven't tried it and it's not enough to 
route as some splitting is occassionally needed).

The first task could be as simple as right-clicking on the tag you want
to extend the selection for (mostly one would be doing names). Kind of 
auto-find without need to write the actual find line (but needs to take 
connectivity into account I suppose).

I also dislike this format. Such shorts are horrible. And if 
autogenerated by tools anyway why not autogenerate the full versions!?!

I don't have any idea what you're now talking about. What are the simple 
(and useful) tasks you can do, if the most roads are there already, which 
do not involve stuff you'd define "minor information" (which I find highly 
subjective btw, I find the physical number of lanes pretty relevant)?
