Yes.  The combination works because (a) abbrev is for those very
commonly used addresses so having them expand on , or SPC means no
thought at all, (b) ecomplete shows possibilities as I type so I will
hit M-n if/when I see what I want, and (c) eudc (TAB) works any time to
complete by typing incrementally.

Not yet sure; my initial view had been that TAB completion (i.e. via
EUDC) would be what I needed for all cases but I'm actually quite
comfortable with what I've ended up with.  However, given that I use tab
completion everywhere else, it probably will be better to have
everything as an option via eudc.

No, I would expect it to provide all my possible email addresses: union
of bbdb, abbrevs, and ecomplete, just as M-x does for me right now with
selectrum+consult, with most recently used or most popular first.

Ummm, interesting.  No idea what I would expect!
