I like having two points in mail ... 8^)
1) This was news to me. I didn't know about this bug. However,
a bug is defined as "implementation doesn't match specification"
and its not clear which we should change in this particular case.
I think the original question was "is wordexp() needed by processes
which run before usr is mounted?"
This should be addressed, but there are many ways to address it.
Having an appropriate shell variant on root is only one way.
2) Are you expanding this case to include fixing wordexp()?
For the reasons in bullet 1, I wouldn't advise that. Do you want
to tie that debate to this case?
If you don't expand this case to include it, then you've only got
a *possible* use in fixing wordexp(). That has value (as a
point for /sbin/ksh93), but only partial value because we might
not decide to use it in this way. (Or the bug never gets fixed,
or whatever,...)
