I never felt the need to work hard to disconnect from Minecraft’s auth servers - but I think I remember doing some command line foo once when the Minecraft auth servers were down for a day, in order to let current players keep playing.
Anyway, all that to say, I think are ways to work around that. It’s not ideal, but probably manageable.

That’s pretty good summary of Luanti.
The interesting nuance is that Luanti was originally built as the engine for making a faithful Minecraft clone, so the two popular Minecraft clones are extremely faithful to Minecraft, in ways that a clone built in another engine could not be.
