Thank you. I see that you are seeking a better solution and looking at
the problem from an angle that I didn't have.

In general, I don't see much consensus on my proposed option nor other
people explaining that it'd be useful to them.

Good.

Thank you for proposing this solution that I did not see. It certainly
has beauty in that it really solves the problem at hand in a simple way
without expanding existing interfaces. I'm not sure whether it works in
practice, but I think that patches for making it work would probably be
accepted in the relevant packages if it doesn't.

To me, this looks like a better solution of my original problem.

Your persistence on this matter is welcome.
