I'm not sure what impact this will have on applications such as Friendica and other macroblog applications. Here, the AP Fediverse is only part of the federation. The Diaspora protocol in the Fediverse expects an article type in order to display correctly. AP claimed to also take this project into account. This was implemented in the AP specification at the time.
The FEP negates longformers in the Fediverse by downgrading them to a blog view across the board. However, blogs are only one variation. The Fediverse would lose rather than gain from this.

In my opinion, the changes described in the FEP involve unnecessary overhead. All this just because a project does not want to implement AP in a compliant manner?
Of course, every project has the right to implement things as they see fit. But if that means that everyone revolves around this circle, then it is a monopolised protocol.

The social web is not a modern invention. Fifteen years ago, this was already the goal of all projects. This requires consideration beyond protocol boundaries. Diaspora continues to be part of the Federation.
