I just poked on the demo and I think it could, however it might be a bit clunky. Maybe could be a viable thing to request of the dev. Maybe alongside a donation for a sort of bounty.

I think the point they’re making is you can effectively have a self hosted non federated option with Matrix. Just disable federation as a whole (which I’m pretty sure is completely possible. Given companies use matrix for comms, and might not want federation, for similar reasons to what is being discussed here)
