Yeah I know of those regression tests, but a lot of the rule system would
not require a (postgres) DB to be spun up, but could often run on a higher
level, e.g., by mocking the higher level methods; iow. more like integrated
test that, while covering a smaller/more specific surface area, can be hosted
in the pmg-api repo directly and run on every package build, vs. the more
complex integration regression test suite that also contains some possibly
sensible material. I mean, the existing regression tests are half-way between
some suite that tests explicitly the external API/mail-transports endpoints only
and some internal testing done.
Also, you nobody mention that you have added, or will add, explicit tests for
the new features ;-)

I hab more a switch for the "Match Group" in mind, i.e., to configure if it
should act as and, or as or. But, tbf, I did not worked with the PMG rule
system that closely in recent times – maybe I'm just missing something here.
