I don't have any problem with the concept *in itself*; in fact I know
of another reason to have something like it. That is 'generic' tests,
tests we want to run on all packages, or at least a very large set of
packages - like the tests currently running in Taskotron, which are
generally run on all packages (rpmgrill, rpmdeplint...) or a large
subset (the Python tests).

What I did think was maybe a concern is that we should figure out in
advance the squishy human consequences of different technical

Basically this boiled down to "who is responsible for these 'shared'
tests, and who gets to decide which 'shared' tests can/should block

Looking at the proposal, I think it actually has at least workable
initial explicit/implicit answers to this, if I'm reading it correctly.
Anyone can create a shared test repository (and is therefore
"responsible" for maintaining it), but the definition of which tests
are run on which packages remains in the package repositories. Thus the
package maintainer(s) retain the ultimate choice over which tests are
run against their packages (and thus can pick which shared tests are
run, and disable shared tests if they are no longer properly testing
their package).

The question 'who decides which tests block which packages' is left a
bit up in the air, but in fact no more so than it already was for
package-specific tests...
