And I was going to add that if you're in a v6-M environment then Thumb is all you have anyway – that architecture has no Arm state at all.

But now I write that, you've made me think of something else: architectures earlier still, like v5 and v4, support both Arm and Thumb but don't have `b.w`. In those, it's probably a better idea to use Arm-state jump tables unconditionally, precisely to avoid having to do this cumbersome stack-based branch!
