The issue with that is that then the Separate and Weld functions become fairly hidden away and a lot of people will not end up knowing about them at all...

For some kinds of things it's not so bad for things to be semi hidden and just as you become more advanced and learn more things you find out about them. But separate might be just a bit too important to do that with, it's needed frequently in surface modeling.
