I'd say "might be split" - we're describing a possible situation, not encouraging people to do it. I think you need another sentence such as "The note should contain a strong warning against splitting surrogate pairs."

I'm actually inclined (without having checked the spec) to think that the spec should normatively prevent the splitting of surrogate pairs.

Well... frequently the spec can't prevent it. It can only make it non-conformant. :) But it can still happen.
