Is there a reason not to just point such users to
or provide the redestributables in an apps installer if it has one?

Even if we provided an alternate implementation that considered Win9X to
have char based native path strings, we still have to do conversions
between strings and wstrings; filesystem::path traffics in either
regardless of the native platform. Since the default conversion has to be
the one provided by the operating system if any, we still can't get away
from needing the Microsoft Layer for Unicode on Win9X.

The idea that the default conversion has to be the one provided by the
operating system (if the O/S supports conversion between wide and narrow
character paths) isn't something that I invented. It has been mentioned by
a number of the developers with actual wide/narrow experience that I've
asked for advise over the last couple of years. I can think of two
committee members (not from the same company, either) who were really
adamant about it.
