using bigger (legacy) wire for smaller amperage


OK, does that circuit for bathroom outlets have to be 20A (i am in USA) and is the reason for that the proximity of water supply (the same reason you use GFCI outlets)? just curious

Yes, it is required to be 20A, I doubt it has anything to do with water. It is much more likely due to blow dryers and curling irons.

If you really want to dig into more of the nitty gritty of why things are the way they are in the NEC, there are many such discussions on the Mike Holtz forum. Many of the people there are involved at least in submitting proposals for the NEC. Nothing wrong with asking, but most of us here are more hands on / real world, and we just work with the code the way it is, and don't have any secret insight on why it is the way it is. We can just make educated guesses.
