so “plug-in hooks”?

Looking back at the original post, I just got more confused:
“This release also adds an inspector panel for block hooks, tentatively named “Plugins,” that displays blocks available for auto-insertion.”

We are talking about a name for what they here call “block hooks”, right? So why not just use “block hooks”? (I presume, following strict grammatical rules, that this is not suggested as a name for the panel; if it were, it would be “which displays” not “that displays”).

If I read your comment right, though, this use of hooks is not truly accurate, so I am now completely out of my depth.
