Legacy home vs. New home Reporting

Thinking out loud:

We have been transitioned to new Home. This means, currently, newly created users immediately go into new home, IF they click on the Home icon.

I'm not sure what happens with existing users but I would guess it depends on whether or not they have toggled back and forth between the two homes.

Here's what I'm observing when I look at the user preferences (where this kind of info is stored) (sample screenshot)

1) for any new user that has not yet gone to Home, they store no preferences for what will happen when they finally go to Home.

2) for any new user that goes to Home now I see two new lines created:

home-workspaces-ftux-acknowledged - true

home-workspaces-opt-in-acknowledge-beta - true

3) for any user who toggles back to legacy I see one additional line:

home-workspaces-opt-in - false

Which brings us back to your question: what does it mean when you are looking for someone who is not currently using the new home experience. Does this specifically mean everyone who has toggled back to legacy home? (opt-in = false) Or are we also concerned with line 1 (people who never went to Home to begin with)?

If it's just the former, I feel like my old code will still work (you just want to change "true" to "false"). Link here:

I would like to identify users that are using legacy Home. Any ideas on how to report on that?
