So the new gTLD round is open right now, we're getting more TLDs whether we like it or not. Our goal is to make one that has features built-in which cater to the self-hosting use case. So that is our key differentiator, that every endpoint leveraging our TLD should be someone's small-scale homelab setup.

Technically yes it could work, but given the suite of features we'd like to build into our TLD, it would make things more difficult if we didn't own it. We would be dependent on external parties for our root domain, the root of trust for TLS certificates, all users' subdomains would have an extra dot etc.
