I believe there are more advantages, but yes this is the primary one.

Address completion in message-mode is messy. There are a couple of
different places where EBDB can insinuate itself into the completion
mechanism: the one that happens by default shadows `message-expand-name'
with `ebdb-complete-mail', which runs its own live-search completion
function, you've seen that above.

The other option is to set (the variable) `ebdb-complete-mail' to the
symbol 'capf. This will put a pre-defined list of "name <email>" strings
into the completion-at-point-functions hook. Then TAB should offer those
strings for completion, using corfu.

The search is less powerful because it doesn't use a dynamic lookup, but
it should still be fine to use.

Let me know how that works!
