Thanks! Small victory, indeed. I created gpg keypairs locally, revoked old ones and added new using Curve25519 recently -- mostly for learning/experimentation. I only use them to sign files locally now (private journal). I've thought about putting them on a keyserver, but I also have a separately generated keypairs tied to my email address provided by the email service vendor. So I haven't really thought through which keypair to make "official" and push to a keyserver...
