Well, in itself, no. But it is certainly helpful for bridging
frameworks when one has a standard way to exchange machine structures.

I agree, and we deliberately only use a subset of SCXML's
functionality, with other features being rejected at design time.
However, everything that I want to express in a state-machine
language, I can express in it. That's a very good start, in my
opinion, and something that is otherwise lacking.
