Has standard.site converged?

I trying out another atproto based blogging tool, and like the others it says it supports standard.site which seems like a good thing.

However it has created me a subdomain on its own site again, and didn't offer to edit or share the standard.site post I made with pckt.blog.

So if each post is actually served on another silo webpage, what is the standard doing?

With previous blog standard APIs - Meta Weblog, Atom Pub, MicroPub - different clients could post to your own blog. The same applies to the bsky schemas - posting those shows up in all clients at the same URL.

So why do the longform tools create a siloed website per tool?
