Hey @Timothy Bradley what do you mean with insecure encryption? There will be a forward path for upgrading your main feed to another main feed. The main benefit being able to use another feed format.
@Timothy Bradley the main problem is that once a key is compromised its very hard to do anything sensible. fusion identity would allow you to first say that the old key and new key are 1 identity and then later tombstone that identity and redirect to a new fusion identity only containing the new key. The good thing about this setup is that you can specify what happened in the redirect.
