We should be able to get a fairly good estimate by checking our own
sources, GNU ELPA, and code search on GitHub.

If we want to take it to the next level one could download all of MELPA
and check there too.  (If someone has a one-liner or a short script to
download all packages and keep them updated, I'm personally all ears.)
