I don't like the focus-hijacking things because it tends to obscure the parts of the UI that you will have to deal with in the next experience. You are given an accelerated tour that does not match the muscle-memory that you will need when you actually use it.

Raising the visibility of something, or pointing an arrow at it is fine, but don't dim and block the rest of the UI immediately because I might need it for context to understand what the hell you want me to click next and why. If I can't do that, then it's just a forced speedrun of 20 steps that I will immediately forget.

It feels like many of these forgot that the point is to teach for the future, not to boost extremely short term interaction metrics. Showing (much less a single time) is not usually enough to teach, you need to establish context so they understand why instead of just what, and generally offer repetition.
