Yeah. :-) Another point of view:
Well, me, personally, I continue to do most of my research using
Python 2 because I cannot afford to port everything to Python
3. And since I do only number crunching, meaning nothing with
security implications, I am not particularly worried.
[...]
Once Python 2 lives in a largely isolated package sub-universe,
I don't see much harm keeping it in Guix for now. If security
issues become apparent, we might have to do something more
drastic.

And if you filter by ’python2-’ from the dashboard,
<http://ci.guix.gnu.org/eval/359297/dashboard>
many are broken but many are still fine.
BTW, ’python2-biopython’ is broken in the branch
’purge-python2-packages’ and still there [1].

I agree and I am advocating since 2019-10-31 [2] for an explicit
plan. :-) However, my understanding of this plan after several
discussions is: remove the python2- variants once they are broken.
It appears to me surprising: we do not provide a schedule for the
removals, then bang purge.

Well, as a hobbyist, I am fine with such purge. As a scientific
practitioner using Guix at work, it is more annoying…

…for instance, I use time to time the package ’bamm’. Because inferiors
and time-machine, the removal of ’bamm’ is not a big deal per se but I
need some time to adapt some scripts, etc.
Other said, I am fine with the purge and I volunteer to help in
transferring from master to guix-past but we need a schedule,
communicate on the purge and more importantly say when it will
happen. :-) (maybe not a purge 2-3 days after an announcement on
guix-devel following 2 weeks in a branch ;-))
Cheers,
simon
PS: Great script, BTW. :-)
