Remember that documents these days will usually be encoded in unicode anyway; the big advantage to xunicode is the backwards compatibility aspect providing unicode definitions for the standard LaTeX accent commands. TIPA is not among these.

It might be that we can only incorporate xunicode into the EU2 encoding to avoid problems with backwards compatibility in XeTeX. If Ross is stepping back for supplying xunicode for LuaTeX, I see no problem with incorporating its features into euenc.

If it were me, I'd just do the following, for XeTeX just load xunicode,
for LuaTeX, just rewrite xunicode the lua way (for example, make tables
of character categories and small lua functions that loop through it
and feed TeX with the definitions macros, get ride of TeX hackary, etc.)
so it is either to read and maintain for mere mortal, then incorporate
the new package with euenc. The luafication might not be needed on the
short run, but as XeTeX compatibility is not need, we should go the lua
way from the start (remind you of my ulterior motive; less TeX and more
lua).
