It’s not an issue if your email is primarily for newsletters, bills and other one way updates (where you are not frequently conversing back). You’ll rarely have to create an actual functioning alias in those cases because a catch-all would do reasonably well. If you are conversing with people it’s unlikely you are going to create an alias for each person specifically, that’ll come across as super shady TBH. So it’s not a major issue for most people because most services support 30-50 aliases easily.
