It looks like the TAP format is winning the competition for a standardised test log format. Perl supports it natively, GNOME is moving to that being the only output format, Meson supports it, and there are TAP modules for Python.
Assigning to RP as he's the architect. Perl uses TAP natively. GNOME uses TAP natively. Meson uses TAP for build-time tests, so if it gained the ability to install test suites there's a good chance it will use TAP too. Python has TAP unittest runners (pychotap, for example).
Maybe make ptest-runner work with both formats?
