I appreciate your feedback on this--I did end up finding the Mouse Model documentation after a bit, but I think there was some frustration built in on my end by that point.

I'm certainly open to trying it again in the future, and honestly do hope that it becomes a feasible alternative at some point. In fact, I think think that for certain tasks, it's not that far away, but I think that some of the UI decisions, whether from expert blindness as you've pointed out or other reasons, will keep coming up as a point of friction for even moderately experienced CAD users from other programs unless there's a deliberate decision made to try to make the defaults and jump-right-in process more familiar to those coming from the existing options.
