Given the US recently made a bid to fast-track multiple censorship bills, KOSA included, and is also trying to kill Section 230 now, which will pose an existential threat to Fediverse instances hosted over the clearnet, how feasible would it be to host said instances over Tor/I2P?
If you detach the origin from the host it’d work, aka HTTP Alternative Services. Firefox used to (maybe still does? idk) use it to silently switch from using the base hostname to a hidden service when running under Tor, when the site provided the mapping.
Clearnet stuff would work without it, but any I2P/Tor support needs server integration, which would be non-existent at the moment I’d bet.
