To the best of my knowledge, all or almost all Orthodox people in the U.S. eat only glatt. I doubt one can even find non-glatt at a reputable butcher. Due to the high standard of living of most Orthodox, this chumra has been well accepted and is easy to observe.
However, this uncompromising and modern chumra comes with a heavy ideological price tag. One can throw out the vast majority of hilchot treifos, as these halachot have become irrelevant. Not glatt? throw it out or sell it to the goyim. For more than a thousand years, poskim were consulted to make a halachic decision on kashrut that made torah she’be’al peh a living torah and not an ancient relic. I am not advocating eating non-glatt meat. But I do not think that it should be a litmus test for inclusion in the frum community. No one would question a Posek’s authority to pasken hilchot nidah, an area which has not undergone modern revision. When a posek sees a mar’eh and paskens l’heter, no one questions this heter, that’s why we go to the posek. But for treifos, a deision l’hatir has become obsolete. it is unfortunate that any question of glatt/not-glatt-but-kosher has been sent to the dustbin of halachah.
