Sure, but is it worth the transition noise?

The way we lightly utter the word "deprecated" around here probably
does not align well with the way how end-users perceive the word.
Just marking something deprecated in a corner of the documentation
set, without actively making an effort to wean the existing users
off, while happily accepting the existing "deprecated" practice, is
what we've done.

In those repositories people have with "[foo.bar] key" syntax that
were created before or after 2011, we first should start issuing a
"that syntax will no longer be valid---I'll update it for you if you
want (y/n)?" warning and keep it for a release or three before
finally removing the "feature".
