I always thought it was totally normal that opener's suit rebid, cheapest notrump rebid, and simple raise of responder's suit were all NF.
That's exactly what I do in my partnership with Brad Moss, but my perception is that this approach is definitely not normal.
When I played with some of Canada's leading players we used the rule "new suit at 2-level always promises a rebid below game".
I have also played "new suit at the 2-level is forcing to 3 of that suit".
I have no strong feelings as to which approach is best (whatever that means). It wouldn't surprise me at all if the right answer (whatever that means) varies according to things like form of scoring, vulnerability, etc. Partnership factors like opening bid style, if 2NT by responder would be artificial, etc. may come into play as well.
