It's probably a hard problem to solve generically. Word has a little popup when pasting where you can select how you want that paste to be applied: Just text, text with its original formatting, or formatted text, adjusted to the document styles. So far I've used all three, so I guess there's no answer that fits all use cases.

Yes, I was going to say the same. Word (incredibly) gets this right.
