Sure; more granularity++.  I haven't put any thought on this though so
please propose something :)

Whatever we decide, 1) these variables need to be documented in
tests(7), 2) a ready-to-enable template in
ports/devel/kyua-cli/files/kyua.conf.in about them would be beneficial
and 3) src/projects/jmmv/autotest/ should switch these on.

They don't AFAIK. The thing is that not that many tests have
side-effects because the majority of kernel-level tests use rump to
avoid this problem and be more reliable/deterministic. The few that
have side-effects have ad-hoc cleanup routines.
