I noticed that some of our builders were failing to build the latest
-next and it was after this commit that things broke. The builders
have an older version of python3 and the gen_headers.py script fails
in a couple places with syntax errors. The following changes
resolved the issues for python 3.5 ...

I know that anything before python 3.8 is now EOL, but I did see a
similar thread on dri-devel [0] for supporting python 3.6 and so
wanted to see if there is any objections to the above?
Thanks!
