Hi Jorg,

I somehow totally missed your answer. Of course I'm glad to provide a
proper patch (and get rid of those awful advices in my init.el ;) ).
Indeed I was searching through my old reports at debbugs mainly in
order to push this one ahead, so it's nice to see you interested
(although a bit late from my side...).

I'm attaching a patch adding a new customization option to suppress
highlighting. As soon as you apply it I will be submitting the
corresponding PR to elpy in order to have full python highlighting all
along the line. The patch is against emacs 27, please let me know if
you have any problem applying it on top 26.

Best regards
