I appreciate the new option "import-drop-uids", however, it always drops UIDs, even if the server has some.
I'd like to see GnuPG accept TPKs from the server that do not carry UIDs by default. "import-drop-uids" overshoots here, because it also drops UIDs if present, and can therefore not be made the default.
In https://lists.gnupg.org/pipermail/gnupg-devel/2018-October/033969.html Werner points out that updating a TPK for subkeys or revocations is useful on its own, even if the server has no UIDs to offer. In fact, if the server has valid new subkeys or revocations, I don't see any reason not to import them.
With this change, GnuPG would be able to make full use of hagrid, a new keyserver aiming to replace the SKS server, where people can opt-in to have their UIDs published.
As a Debian user, I'd love to see this feature backported to 2.2.
