Thank you for taking the time to respond. Well, my old projects still work and look identical, which is what's confusing. Although I can't set keys on new draw objects, and the existing objects don't show any transformations on the curve editor or the dope sheet, they're still there somehow. So, theoretically, it should still be possible to do.
Still, I think I buy the logic of this not being an intended behavior, although I must admit altering a bounding box is ten times easier than managing double the objects and using the finicky transform gizmo. It's just that now I'll have to keep track of so much, but I think I can at least make it easier to digest by hiding the unchanging attributes from the options panel (whatever it's called on the right). Using an older version would be more annoying, especially since I keep updating the dependencies here on Linux.
Yeah, I think I'll dig for an existing bug before making a new one so I can at least know how I'm supposed to do this kind of thing. I think I'll also argue the point that it should remain since it's more intuitive and efficient, in my mind. Thanks again for your willingness to speak up.
