Does anyone use M120 or M121?

did, but I can remove them all easily utilizing that "any time that a macro is called a push and pop are done around the macro call automatically" ... most of them I have on start and exit of the macro so if that's done automatically ..

With variable declaration, I believe @chrishamm and anyone else can write their own push/pop routine and store/restore any variable they like?

Possibly, but they should have at least one release where they can test old and new version to make sure they behave identically.

Deprecation always is tricky.
