[Bf-committers] Why must sync selection be disabled to select UV islands?

[gandalf3]

I would be surprised if this hasn't been asked before, but finding old 
stuff on the mailing list isn't easy..

Anyway, trying to select UV islands with L while sync selection is 
enabled gives the error "Cannot select linked when sync selection is 
enabled".
Why must sync selection be disabled? I can't think of any obvious reason 
why there would be a conflict of some sort.. As a matter of fact this 
seems like it would be a really useful ability.

Is there some technical limitation which prevents this?
