I love that age lets one reuse ssh identities and thus identity sharing systems. The single most useful thing I ever wrote was a tool to sync github identities with age.

This way you get git for change tracking on your secrets and who-has-access-to-secrets and key rotation and this can be trivially expanded to other forges.
Its easy to introduce age this way into any modern project whereas gpg would-ve been a non started on most teams I worked on.
disclaimer: this was mostly vibe-coded because I really did not want to work on this and wasnt sure if teammates would adopt it. Then it just worked, so stayed ugly inside
