Use without nsec.app NIP-05

[snarfed]

Hi! First off, thank you for building and maintaining noauth and nsec.app. They're great!

I have an existing Nostr account with its own NIP-05, and I'd like to use nsec.app with it. I know I can import my nsec, but I don't want to switch its NIP-05 to @nsec.app. The nsec.app onboarding flow currently makes me choose a username @nsec.app, so I assume if I do that, it will update my account's profile and write a new kind 0 even with the @nsec.app nip05? I know I could then update my profile again myself and switch it back to my own NIP-05, but will that stick? Will nsec.app ever rewrite that profile event again with the @nsec.app NIP-05? Any other thoughts on how I could do this, or if it's just not supported right now?

Thanks in advance!
