It is t.

It is currently nil.

The behaviour I described was when I was testing with TAB bound to
message-tab, yes.

Can you reproduce the scenario in your screenshot, then subsequently
type '-' then TAB, to complete on "emacs-" instead of "emacs"; I think
the completion backends will be queried again.  That's what I want to
avoid (if that doesn't happen for you, then I'll have to recreate my
testing environment and test more carefully with all the combinations of
the above variables, I guess).

Did you confirm completion-table-with-cache is doing something?  If so,
do you mind adding a comment within eudc-capf-message-expand-name's
body, describing what the caching is doing, when the cache is
invalidated, etc.?

Thanks,
Thomas
