I don’t care about Reddit (or about growing Lemmy) as much as the average post I see in Lemmy, but if you wanted to migrate people from the former to the latter this is one of the easier ways to help do it. It’s one of those small quality of life things that are asked for periodically. If Lemmy had it it’d be mentioned in Reddit every time people are pissed with the site (which is every day for most sites, including Reddit). It’d be free mouth to mouth publicity for Lemmy
