That's probably true.

I have been viewing test-suite as a kind of second-level/backup testing
that catches things not flagged by "make check-all." Is that a
reasonable interpretation? I was hoping to get some end-to-end tests
under "make check-all" because that's easier for developers to run in

Yeah, I saw that. I will see if I can attend. There are some conflicts
we have to work out here.

Is there a proposal somewhere of what companies would be expected to do?
It's difficult for us engineers to talk to management without a concrete
set of expectations, resource requirements, etc.

Nice! That's much better. Yes, it won't scale but it's much clearer
about what is being run.
