I think there should be a handoff procedure, or whatever you want to call it.
As EOL approaches, work with whatever open router OS maker is available (currently OpenWRT) to make sure it’s supported, and configs migrate over nicely. Then drop one last update, designed to do a full OS replacement.
Boom, handoff complete.
Most of the furry artists are moving to Bluesky anyways, so it’ll be worth your fapping time to start checking there as well.
But for the artists that haven’t moved? Yeah, go ahead. As long as you also archive it locally to cut down on revisits.
