I have developed ActivityPub software, I am aware exactly how difficult it is to implement - which is less than what Hrefna's thread would lead one believe.
I think the main thesis of what she is saying is that there are a many places where developers need to think for themselves because the spec has many blind spots. But that's why we also develop tools and libraries to make it easier for future devs to start from a good foundation. She is doing it (as far as I know), and I am doing it.
