This could be done, of course. But it would add additional complexity to
simple.el, although a better solution could be implemented.

Mid-term somebody else will write another bug report for this. If we're
going to fix this bug, it shall cover this aspect as well.

Yes, I'd like to go this way.

It would be impossible to explain why it is restricted to just this
use case. And people would blame us.
No, I would like to take the opportunity to introduce connection-local
variables. First it needs a proper API.
Best regards, Michael.
