And doubtless the reason why I chose that for  xunicode.sty .

It looks like there are some other assignments made in \activatetipa
that may not be correct; viz.
    \def B{\ss}%
    \def G{\textbabygamma}%
    \def U{\textscupsilon}%
    \def Z{\textezh}%
    \def 3{\textvarepsilon}%
ought to be
    \def B{\textbeta}%
    \def G{\textgamma}%
    \def U{\textupsilon}%
    \def Z{\textyogh}%
    \def 3{\textrevepsilon}%

Sure.
Back in April 2006 I wrote on this list:

There was a little bit of further discussion in that thread,
but nothing much seems to have been done.

Surely it is best to get the errors fixed as soon as possible.
