It is indeed unfortunate that these bugs in the community document server are not fixed (or that it only works on x86 for that matter), but if you keep in mind to only use the web-editors (or the OO Desktop editors) it does work somewhat satisfactory, so removal seems not necessary. A big warning should probably be added though.

I have a love/hate relationship with Nextcloud for how bad they neglect personal users. They advertise as being an amazing cloud host solution for everyone but unless you use a partner provider you can’t get support as a personal user. Even the “gold” Nextcloud hosting providers will say they are powerless when it comes to fixing issues because they’re not paying for enterprise support licenses for their personal users. So we’re left with these long running issues (I have tickets that have been open since 2018 that are still not resolved) because Nextcloud GmbH has no incentive to fix.
