Hear, hear.

gem_seqno_wrap is defunct as the debug API withered away. The
handling of wraparound under many different workloads is tested by
gem_exec_whisper. The intention is to may seqno wrap handling a
kselftest. That hasn't happened yet, gem_exec_whisper is not run wholy
by CI, but nevertheless gem_seqno_wrap is still defunct.

gem_pin is a useful ABI I still shed a tear over. But it's time has
passed and it's not coming back.

gem_hangcheck_forcewake has been superseded by drv_hangman, and a lot of
other very extensive hangchecking that is not run by CI. Something about
hang testing taking longer than the sun to go nova, and still will never
be completely reliable...
