Not instead, but to rpm *too*, yes.

Quite obviously an action that's currently done from say %post script 
should stay at rpm level, moving some things to be only done once per 
transaction is just an optimization really. But yum knows a lot more about 
the surrounding world than rpm does, such as which repository a package 
came from which is something rpm has no clue about, and thus it can do 
things in post-transaction that rpm simply could not do. I don't have an 
example use-case in mind atm but I'm sure somebody can come up with some 
relatively sane example ;)
