Should they add more non-Federation mirror universe ships or should they focus on proper new content?

Back in the old days they used to add these weird little mirror universe T5 ships in lock boxes that were basically the exact same as the normal ship but with a sliiightly different boff layout, maybe some different consoles and access to a mirror universe skin.

Nowadays we have quite a lot of T6 Mirror/Terran ships for the Federation in the Zen store, from events and from lockboxes. But afaik no new like klingon mirror ships. At least I haven't noticed any with like Mirror in the name.

I just feel like there's a big untapped potential for mirror universe stuff that's not the Terrans. Especially since it should be **relatively** low effort to produce as long as it's just a reskin with a new skin trait and console.

Like fucked up evil Mirror Pilot Bortasqu.

Ok sure apparently the Klingon-Cardassian Alliance was defeated but that doesn't mean w/e they were using in the MU should be completely lost.
