Pretty sure that's just Harry's early quest. (Which seems like a lot of fun if he got stuck that way, just to mess even further with the canon). Only other bits of transformation so far I can think of is learning to conjure up a dongle to dangle as a female protagonist for one sex scene, and Tonks showing off her innate talents in the baths.
It's inferred that one may even be able to tweak physical characteristics down the line (huge tracts of land or be a shower *and* a grower) but none of that is in yet.
