The proof of the planned data collection, confirming my previous claims, found declared in the source of the extension itself:
"## Observed data
- Possible page view counts on SUMO
- Possible page view counts (with and without the special 'enrolled' header) on Partner pages."
I've also already explained the "special 'enrolled' header."
The turning on was obviously either planned for some special moment, which wasn't the moment of that the extension was actually delivered, or the extension was accidentally delivered in the unfinished state -- doesn't matter, it provably didn't get enough scrutiny, see my other comments here for the details, the damage it actually done is regarding "tracking" less than planned, but regarding annoyance of their users probably more.
