why?

for anyone to be able to run a server, without all the specialty random interactive hardware.

what?

make it so the entire server and web UI can work with ONLY ROVERS and nothing else
make sure that any extra feature can be disabled server-side, and when disabled it disappears from the web UI without a trace. no empty panels that say "nothing configured"
ONLY mess with features that require extra hardware.
make all extra integrations that arent only software be disabled on install, so if you want to add support for one you enable it manually.
