seb128 says Trevinho is likely to be working on this.

Judging by
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=936515 and
https://salsa.debian.org/mozilla-team/firefox/-/commit/1e04e9b9d95c9efde7928bc41804cc20a1bb868b
it looks like we might be able to avoid Python 2 in the build system
for this one.
