Hmm... not sure I understand.  I was proposing to add it to the EUDC
code in Emacs (e.g. `eudc.el`), not to the Company package.

I think it would make a lot of sense to add such a CAPF directly to
`eudc.el`, and then to hook it into `message.el`.

I must admit, I don't know where `company-eudc-expand-inline` would end
up in that scenario, tho :-(

We could add a config var to control whether EUDC should be queried in
by default in `message-mode`, and we could easily add a command that
runs `completion-at-point` with EUDC's new CAPF enabled, but it would be
odd to run `company-begin-backend` from Emacs core code.  I guess we
could have a command that either runs `completion-at-point` or
`company-begin-backend` depending on a config var (e.g. whether
`company-mode` is enabled), but it would be nicer to make it work with
other completion UIs, like `corfu-mode`.
