This is a very important thing to remember. OSM has a very small number of sysadmins who do Trojan work, and have limited time. When I wanted an OSM Mapstodon server/instance, I knew the sysadmins didn’t have enough free time especially for something (at the time) with such low usage, so I just got a paid SaaS service.
If you’re asking/demanding that the sysadmins do this thing… well you might be in for a bad time. If you wanna set up a gitlabhubforge yourself, go for it.
