Should KUnit be the first name here? Then all KUnit tests appear in the
same location in the MAINTAINERS file, or should it be like it is here,
so that KUnit tests are close to the same-named area?

Similarly for the Kconfig name. (Also aren't KUNIT and TEST redundant?)

config KUNIT_LIST

?

config LIST_KUNIT

And again, list-kunit.o? Other things have -test (or more commonly
_test) suffixes. (So maybe list_kunit.o?)

But as I said last time, I'll live with whatever, I'd just like a
documented best-practice with a reasonable rationale. :)
