Yes, agreed. I think there's some validity to this - with the GPUs on these much more capable than the ones on the M1 MBA/13" MBP, it's not exactly apples-to-apples to compare experience using 16gb memory on the M1 models. The GPUs on these, depending on what you're doing, may end up utilizing more memory.
Once I convinced myself to bite the bullet for the steep price for 32GB memory upgrade, the "problem" now is going from M1 Pro 10/16 to M1 Max 10/24 is now just $200... On my 14" which is already $2899.
So just $200 to get 8 more gpu cores AND double the memory bandwidth (from 256-bit 200gb/s to 512-bit 400gb/s). I don't need it, but there's Apple upgrade pricing for you at its finest! If I was sticking with 16gb memory, then not really an issue (because you HAVE to be at 32gb memory to get M1 Max, which would be another $400), but once you're already decided on 32gb, well...
