To be frank, I would prefer keeping hasBlendMode() but make it as simple as
hasFilter() above. It's pretty common in rendering/ to have such helper
functions. It would also remove a lot of the churn from this change.

That said, I won't fight strongly to keep it.

Yeah, I can kind of agree to that - I wasn't really expecting this level of
churn...

Let's hear what Chris has to say.
