It's close enough and has been already in use. A regression of features quality - for example.

There's no reason to coin a new term at all, nor chasing this idea of using long German word as a replacement.

It works, but regression is broader. If I'm not mistaken, a regression can also happen without human intervention. Verschlimmbesserung is active. Someone actually tried something and made it worse.
