Lookups by file names have they disadvantages too: 

In my backups I can find various libertine versions:
LinLibertine_Re-4.4.1.otf, LinLibertine_Re-4.7.5.otf,
LinLibertine_R.otf, fxlr.otf. 

Documents which call this fonts by file name would have to been
rewritten constantly. And if the versions had always used the same
file names, then probably a version installed in the system would
conflict in the same way as by font name lookup with another version
in the texmf trees.

Well I don't think it is only a problem which should/can be handled
only by xetex (or luatex/luaotfload). The TeX-systems should also
(re)consider the way fonts are installed (miktex more than texlive).
Until now (before XeTeX) TeX fonts and system fonts were two quite
separated worlds and the place where to install a font was quite
well defined: TeX fonts in the texmf tree, system fonts in the
system font folder (with a small number of exceptions like the ttf
used by the winfonts package). But current ttf and otf fonts now are
both: fonts used by a tex engine and fonts used by the system. And
it is the question if such fonts should actually be in a texmf tree.
At my opinion most users would prefer to install this fonts only
once in their system. (And - even if it is confortable - I don't
think that miktex should add by default the texmf-trees to its
fontconfig pathes.)
