This is pretty nice. I've been guilty of posting patches that passed
check but not syntax-check in the past O:-) and I know for a fact I'm
not the only one who's done that ;)

Jumping in a bit late, but why do we care about this distinction in
CI at all? In our existing setup, for all projects 'make check' is
executed if and only if 'make syntax-check' has succeeded, so the
separation is fairly arbitrary and doesn't really buy us anything as
far as I can tell.

be nice, once a project switches to Meson and its syntax-check rules
are moved to the test suite, there might as well be a single CI job
which runs 'ninja test' and that's it.
