It may not.  XEmacs provides a generic "database" interface in Emacs
Lisp.  The underlying database can be libdb, gdbm, ndbm, and probably
something else I've forgotten.  XEmacs itself only uses that interface
to keep a Unicode code point database.  That is easily recreated.

The problem is that I have no way of knowing what people have done
with the Lisp interface, what databases they may have created.  It is
entirely possible that 0 people will be impacted if I change the
builds to use gdbm instead.  It is also possible that I will get lots
of bugs filed by angry people who can't access their databases
anymore.  I have no way to tell (without actually doing it and seeing
how many bugs get filed, of course).

Sorry, I'm not catching your meaning here.
