So far, the way it has worked is that every AP implementation's content works on other implementations, because AP supports media. The exception is Lemmy, because Topic Threads are not in the AP standard, but that's partially an issue of what other software hasn't implemented.

I would guess that Loops, if implemented correctly, will be viewable from most other softwares, and I'm assuming they will test with Mastodon.
