GPG support? (like SSH)

As others have stated here already, I use GPG-based signing and encryption for the following activities:
* E-mail signing (majority use case) and encryption (not-insignificant minority)
* As the framework for securing on-site incremental system backups and the occasional full volume images
* To authenticate the end product of packaging efforts for various and sundry Linux distribution package archives (this one's the doozy of the bunch)
* Securing P2P file transfers and shares over otherwise less-secure services (e.g. Dropbox, OneDrive, LocalSend, et al.)

Also echoing several others in this thread, the primary functionality that I seek is really the gpg-agent service and less so the key pair generation and management, although ideally they would at some future time all be present in 1Password. Just to be able to import public and private keys exported as individual files (whether binary or ASCII-armored) and have 1P recognize them, display their identifying characteristics (algorithm, key size, fingerprint and comment) and serve them up in response to the standard gpg-agent calls would be more than enough to have me purring like a kitten for a good long while, though. It's the ability to have them available on all my devices in the same manner that 1P already does for other credentials that I'm so sorely lacking in my current workflows; it wouldn't be an onerous hardship to handle the tasks like key signing, subkey and identity addition/revocation and expiration changes with the tools I already have in place so long as in the end the updated key pairs could be returned to 1P and made use of from my other devices.

I hope that provides the clarification you were asking for, floris_1P, if not, I can get more granular.
