It has not (despite the promises for Win2000), but
it's not as bad as you make it.

You waste a lot of the user's disk-space, but that's all.

Nope, multiple DLL's with the same name, from different
directories, can perfectly well be loaded in different
processes at the same time.

The problem has to do with programs installing their DLL's
in _system_ directories -- as they used to have to do (still
do, I believe, on Win/ME) for a few DLL's identified as
"crucial system libraries", such as MSVCRT.DLL.
