@f4grx @pemensik @soatok As some one familiar with the whole stack when it comes to email, it is not that there is any political power holding back adding in something to replace PGP with a working RFC, it is that there is a stupidly large number of projects involved to make it all work and it requires getting every one on board. It is why new RFCs tend to get adopted slowly for it. Takes it's way to make it through the entire ecosystem.
If you want a closer to home example, look at the encryption stuff you've mentioned working on for ActivityPub/Mastodon. So once you get it implemented for Mastodon, there is still every other ActivityPub server that also needs to support it as well.
And here we are talking about a ecosystem that is incredibly small compared to the entire stack that is email.
