I promise, you do not need to explain to me how something _can_ be done in ActivityPub. I am aware that things _can_ be done.
The problem I am highlighting is virtually never "I can't see a _way to do this in ActivityPub_."
It is almost always a question of standards and interoperability and what would be required to get to that point.
One of the core, key, challenges I've talked about in ActivityPub and that I come back to repeatedly is the lack of out-of-the-box interop, ways to demonstrate interop, or ways to prove compliance.
It's easy to say "oh this is a solved problem in MFTS (my favorite toy server)." It's easy to come up with _ways_ to solve it.
That's pretty much never my point.
@hrefna What is MFTS?
@YurkshireLad in the parentheses.
My Favorite Toy Server, a reference to MFTL (my favorite toy language): http://www.catb.org/jargon/html/M/MFTL.html
@hrefna thanks. I wasn’t sure if that was referring to an actual product.
