Not true. It is a matter of agreement, not an automatic part of 2/1. It is giving no headaches to play whatever major suit raise structures one chooses, none of them obstruct the system at all.
It's true that you can play whatever raise structure that you want ofcourse. One can play Gazzilli in 2/1 as well, but that doesn't mean 1♠-1NT-2♣ in standard 2/1 can be done with less than 3♣s.
Maybe it's a difference in culture. If I sit down and my partner says "2/1", then I consider 1M-2M constructive and 1M-1NT absolutely forcing which can also contain raises with 5-7HCP or invites.
