Yes, it's a valid question.  Let me quote one thing from my original
mail that wasn't emphasized very well so you may have missed it:

"(note that when I say 'frontend', it may be the MUA
itself, or it may be a helper client library like some future
libedsmailui library):"

So my thought was that maybe we would have a libedsmailui utility
library (similar to something like libedataserverui) that would
implement these filter editing dialogs, etc.  Then evolution and anjal
could both use them by simply linking to this UI utility library.  Does
that address your concerns?
