Ok. Anyway I've just double checked, and it worst than that.

Typing 'a' complete to 'aA' (instead of 'Anne <mailaddress>') and then
does nothing since aA is not valid.

I'm not sure completion-at-point-functions is correctly usable in this
same dondition as message/bbdb completion was. The latter used to return
a function which is marked as decouraged in
`completion-at-point-functions' docstring. So org-contacts does not use
it. OTOH, returning a (START END COLLECTION) triplet is not very usable
since if you return a collection that start with a different character
set than (buffer-substring start end), it does not work.

(Cc'ing emacs-devel, in case someone has an advice on that.)
