The primary source of members for all the Abrahamic religions are born into it, not converts. Churches, Mosques, Synagogues will continue to exist, as long as they are effective at boosting birth rates for their members, and manage to retain their children to a degree.

Homosexuals are therefore low-revenue customers, because the expected children count (including adoption) is far lower than heterosexual marriages. Churches that prioritize accommodating modern social mores statistically have shriveled massively.

Whether they have 'squandered' anything by sticking to their 'business model' will only become obvious in decades. They don't operate on quarterly targets or even 5 year plans. Judging by fertility rates, highly religious groups still have higher birth rates than secular groups.
