If a fediverse post contains something that the receiving server doesn't support, we need a defined way to show that to the receiving user. For example if I make a pixelfed post with 6 photos and mastodon only shows 4 of them, there needs to be a way to signal to the receiving side that there is content they can't see. This has been an issue forever but one of those little edges that makes the whole experience worse for everyone. cc @andypiper any ideas for how we could make progress on this?

this is rooted in the dogma to ever push the full content and never GET.

Reconsidering this could finally lead to https://www.w3.org/TR/websub/ + GET. A landslide towards simpler #federation. IMO well #worth while.

WebSub

WebSub provides a common mechanism for communication between publishers of any kind of Web content and their subscribers, based on HTTP web hooks. Subscription requests are relayed through hubs, which validate and verify the request. Hubs then distribute new and updated content to subscribers when it becomes available. WebSub was previously known as PubSubHubbub.
