The bulk of the work was done in the earlier patches, and my python
review is weak; but I can confirm that with this patch applied, my usual
attempts at running ./check still appeared to work for me.  That's not
the same as proving you did 1:1 feature translation (and in fact, your
commit message documented dropping some features like -v), but if 'make
check' and CI tools still run, I'm okay leaving it up to developers to
complain about any other feature that they used but which go missing (or
to implement it).

You may want to claim 2021 as well.

A lot shorter for the main engine ;)

Happy to see this conflict magnet go!
