Well if we are going to follow the Rema I look forward to everyone wearing tefillin on Chol HaMoed, eating dairy an hour after eating meat, and going home immediately after maariv on seder night rather than staying in shul to recite Hallel.
Societal Judaism as it is formed today is very much a “pick who you like” in terms of Halacha. If not, everyone would be doing woman’s Mezumenet, which is what all pre 20th century poskim say to do (TTBOMK) (and no yeshivish family does). Let alone Zemanim, Kashrus and Tznius.
