This was what was intended by the first "exemption" listed[1] at the
beginning of the document:
"It's recommended that you only deviate from these guidelines when:
[...] Porting tests to KUnit which are already known with an existing
name"

Admittedly, this test was originally a KUnit test, rather than a port
of another test, so the exact wording probably doesn't apply here, but
that's more an artefact of the naming guidelines landing after this
test did.

The goal here is really just to make sure that existing test modules
can be ported to KUnit without breaking existing users which may
depend on the name. It doesn't look like that applies for this test,
though.

Cheers,
