How long will Rosetta 2 be supported?

I am working on my Apple Silicon transition, and there are a few pieces of troubled hardware I need to rely on Rosetta 2 with -- thankfully it's minor, but the "troubled, can't replace it" list is rough, to put it nicely.

For Silhouette Studio, there's no clear answer on what to do and the Cameo 3 I have doesn't have the BT module to run it on an iPad (optional, used discount). They have given me zero help besides "install Rosetta" -- THIS IS APPLE, ROSETTA IS A BRIDGE; NOT A CRUTCH. I know we got screwed on PPC>Intel, but we know that was due to IBM dropping the product Apple used.
