:-) thank you for caring.

Yes, I think so too. I will try to do that.

Sure, I will do that eventually.

By the way, I started working on fixing the bug mentioned in
comments 2, 8, 10, 11, 12, 13. Now we seem to have the infrastructure to
do so. I will come up with a patch to fix this specifically, on top of
the patcheset of this PR.

Maybe I need a separate PR, I don't know.
