No, I think we should continue declaring them obsolete, because in
many cases they are used incorrectly, and produce subtle bugs.  For
example, in some locales, string-make-unibyte produces the same
results as encode-coding-string, so people could mistakenly use the
former instead of the latter, if that happens to work in their locale.

One such case is in ruler.el; search for "unibyte".  This use case
could be fixed by adding an optional argument to make-string, which
would force it to always produce a multibyte string -- that's the kind
of alternatives I had in mind, which should help us get rid of these
obsolete functions in the few legitimate uses we still have.
