Quite dangerous since it could be felt as a sort of privacy issue.
It must be carefully voiced.

Something like

Feature foo has been deprecated (? for info).  Complain (y/n)?

and then offer the usual "use it this time/don't ask again" dialog we
use for disabled commands.

After a while, one can remove the feature/command and instead do

Feature foo has been removed (? for info).  Complain (y/n)?

The info should explain why something is removed/deprecated and what
to use instead.  The mail buffer should be set up in a way that the
user can add his own comments and send, not just do this silently.
