I know that Alpine caches S/MIME keys that it receives,
but has no PGP support, so this is just for info.
Web Key Directory
https://wiki.gnupg.org/WKD
looks like an interesting way of acquiring and managing PGP keys
with little user effort.
With Protonmail, Debian, Gentoo, Gnupg and f-droid
amongst the providers and organisations using WKD
it may be useful to some people here.
