@NimJay Are the doc inclusions handled?

[NimJay]

@Sita04, thank you for the quick review!

Are the doc inclusions handled?

Good thought. I just left a new comment in the Buganizer to answer your question. tl;dr - The docs already freeze the region tags at a specific commit.

Related question: Do I have to check for doc inclusion manually every time? In other words, would snippet-bot catch any doc inclusions for me.
