Maybe masters will become more popular. I have no problem with bars being raised on PhDs, but it's crazy history that math may be the first one to have it raised (or brought back to old levels).
IMO, I don't think this will raise the bar for PhDs.
In every field of science, PhD student research is largely incremental. Very rarely is a thesis groundbreaking. The point of it is all is to function as an apprenticeship for that PhD student to become a scientist.
Sometimes a particularly gifted or lucky one hits an important result, but that's rare and isn't the purpose.
