Nothing :) I'm working on Njump, that is actually tied to nostr.com like many other tools (ex. nak.nostr.com, metadata.nostr.com) for convenience. If something changes maybe there will be another web access point for nostr profiles and notes that will use Njump, and people will update their link in bio. Domains are centralized by their nature, we can use them as web proxy (same applies for NIP-05), but avoiding blind trust.

Lol
