As a left handed user... I fucking despise the idea of thumb-reach heatmaps geared solely towards right handed use.
As a side note, we make up ~10 percent of all users. If you design to the thumb reach of right handed users by default, you're fucking over a lot of people.
Add on that ~19 percent of the population has some form of disability, and a solid chunk of that involves hand/limb usages, making the head-up-ass assumption that a right handed thumb map is the "ideal" approach is... well you've shoved your head up your ass.

edit: I want to add, I'm not attacking you so much as the general premise of the article. I come off as fairly hostile on this since it's such a common day to day inconvenience for a broad swath of the population.
