Totally agree, and it's too frustrating. Somehow this reminds me of how Apple introduced TextKit 2 with tons of bugs and feature limitations, then silently dropped supporting it or even talking about it—now TextKit 2 is in some sort of limbo and looks like a Schrödinger’s cat. Hope it won't be the case with agents, but the overall inconsistency in Apple’s moves regarding developers is sometimes scary. It's definitely not a way to win developers' trust.

Has someone managed to make it work with menu bar items on macOS Monterey? It seems FocusedBinding and FocusedValue are broken even on macOS 12.1.

Wonder, how did they provide pagination with Text Kit 2 in TextEdit app? As they said in the What's new in AppKit session, TextEdit uses Text Kit 2 since macOS Big Sur.
