minor #11621 Removed deprecated contents (javiereguiluz)

This PR was squashed before being merged into the master branch (closes #11621).

Discussion
----------

Removed deprecated contents

This is related to #11620 and removes deprecated things.

The only remaining deprecation is the `transChoice()` method. I'm leaving that for future PRs because @wouterj created a big PR pending to be merged related to that.
