I think it's probably obvious that no author endorses every list that their
works of authorship show up on.  But I think you were probably joking. 🤣

In seriousness, the list isn't helpful for someone *choosing* an
additional permission because (as mentioned) the list is incomplete, but also
because there is no analysis of effectiveness, usefulness, efficacy and
popularity on that site (by design, AFAIK).  The list gives just enough
information to be dangerous for AP-seekers.  But, you're correct that a true
unified catalog of APs and analysis of them does not exist.

Tangentially, this blog post that my colleague Karen and I wrote might be of
some interest in this context.  In it, we analyze two different additional
permissions that are attempting to accomplish the same task and explain why
(in our opinion) one is a better choice than the other:

While the post is about additional permissions unlike the one Joel is
pondering, the on-topic point there is that there are so many ways to draft
these things, and so many potential pitfalls, and that is what leads me to
first focus on “are you really sure this is what you need?”  questions first.
