Thanks!

That does it:

    # emerge -av --depclean =dev-lang/python-2.7.18-r6

    Calculating dependencies... done!
      dev-lang/python-2.7.18-r6 pulled in by:
        www-client/chromium-88.0.4324.182 requires >=dev-lang/python-2.7.5-r2:2.7[xml]

I'm a bit surprised that 'equery d' is unable to figure that out.

The other option I found is to uninstall python:2.7, then do emerge
-auvNDt, and see why it's being re-installed, but that's a bit
drastic.

And now that I know the answer it makes sense: the machines where
python 2.7 was removed by depclean don't have Chromium installed.
