I'm not aware of any general requirement to maintain backwards
compatibility with ancient Emacs versions on master.  For example, we
have dropped all compatibility function and variable aliases.

Users of Emacs 21 or older should surely just use whatever was shipped
with the version of Emacs that they are using.  Or am I missing
something?

To be clear, this package is not distributed on GNU ELPA as far as I can tell.

Best regards,
