Comment on How did we move from forums to Reddit, Facebook groups, and Discord?

That extension has a definition and Lemmy follows it so in that way it is “standard”. But it is an extension, not part of the core protocol.
Mastodon and most other fediverse services do not support this extension.

Sounds like mastodon and other services ought to really support this extension though.

Sure. But lemmy would still not show Mastodon posts outside communities even if they supported that extension. Both parties need to move towards each other.
