Thirty years from now, when new chumras that I can’t even imagine will be the new norm; someone will write in the coffee room of 2041 about our time;
“Inasumuch as they didn’t keep halacha- yes, they were less frum.”
One thing you can not fault Judaism for, is that we always spell out precisely what is d’oraisah, d’rabbanan, and chumrah. These halachos are spelled out precisely in the poskim.
