You all convinced me. Thanks for the PR, @brustolin, and thanks for all the extra context, @armcknight. LGTM when adding some log messages.

@brustolin, is anything stopping us from merging this?

I’m just waiting to finish the SwiftUI TTID PR because this code was created on top of that one, and I don’t want to add it to the other PR and have it reviewed again.
