The problem is not that the characters in question are *both* polysemous
and polymorphous. You don't have that situation with SOLIDUS &c.
The unification seems to cause more trouble than a disunification would.

I don't suggest encoding a unique "folder symbol" character.
The "folder symbol" is the character at 0xC4 used as a spacesaver. Instead
of titling a directory "Unicode Folder" English-speaking Mac users often
write "Unicode " (might Danish speakers use "Unicode µ" for
"Unicodemappe"?). Apple maps this to U+0192, LATIN SMALL LETTER F WITH HOOK.
If FLORIN SIGN were added, Apple (for instance) would have to make a
decision as to whether 0xC4 were still to map to U+0192 or to the new
character. Most fonts draw the character with its italic florin shape, so
they might want to remap it to the new FLORIN SIGN (which would make U+0192
more useful to Ewe speakers).
English-speaking end-users who care about such things could then make a
decision as to whether FLORIN SIGN or LATIN SMALL LETTER F WITH HOOK were
the appropriate abbreviation for "folder".
One cost inherent to the disunification could be in searching for
directories using the symbol, but as a long-time Mac user I can say that I
have never done so.
