Some people play that 1♠-2♥ (and sometimes 1-♦-2♣) as non-GF where other 2/1 responses would be.
IMO that's throwing out the baby with the bathwater, the essence of 2/1 is being able to describe distribution and force to game at the same time.
We even play 1♣-2♣ as a 2/1 GF over short club openings.
