I don't get it. The wording of the bugzilla specifically says
> The "Compact" density is a feature of the "Customize toolbar" view which is currently fairly hard to discover, and we assume gets low engagement.
So not only do they not have telemetry for that, they aren't even attempting to make it more discoverable to test if there's a correlation between "hard to discover" and "low engagement"?
I would use this but never knew this could be changed.
