If it's purely a compatibility function, then using ICU's sophisticated
word break iterator doesn't make sense.

I don't think ICU purely follows Unicode on this point (does it?), so
we'd have to point to the ICU documentation.

I still don't fully understand the use case here. I've used the
function a few times to assemble a few strings into a page heading, but
that was some time ago so I don't even clearly remember my use case. It
seems plausible there are quite a few people doing something similar,
and they'd benefit from ICU's more sophisticated approach.
But if the primary use case is for compatibility, then we might be
trying to hard to make this a provider-specific feature.

+1.
