The good news is the last season had a flashback to Marge’s high school musical about Y2K that took place before Homer and Marge officially “met” so they couldn’t possibly have been dating in the nineties and that episode has also been retconned.

The truth is neither of those were retcons. Marge and Homer met in high school in the 70s and they on and off dated in the 90s while Homer was in a grunge band (unrelated to the massive success he had as part of a barbershop quartet in the 80s) and also they’re 38 in 2023 and all of these things are somehow true at the same time.
