Like all other third-party browsers, Orion has no Keychain support, no auto-filling of 2FA codes, no support for Hide my Email / Private Relay, and no synchronization of Bookmarks/History with Launchbar and iCloud. Thanks but no thanks, I like my Safari.

Not sure where you got that but for the sake of facts:

Orion has Keychain support.

Orion has auto-filling 2FA codes.

Orion has iCloud sync.

If any one of those are not working as expected you should report it to orionfeedback.org

Private relay is an Apple service that is not available to third party apps.
