Letterboxing makes me more unique

The tor browser's recent letter-boxing is driving me crazy. I lose buckets of screen space, and according to the excellent panopticlick, it only helps a little.

Vanilla Firefox (70.0): a unique fingerprint (I'm on xubuntu), but not a lot of entropy. Nothing in the list of stuff stands out, but my combination is unique. My screen size of 1440x900x24 is 1-in-27, and my fonts are 1-in-70 etc.

Tor browser (68.2.20) with the new default letterboxing: screen size is 1400x700x24 is 1-in-6k but fonts are much better at 1-in-10. The fingerprint has much more entropy than the vanilla Firefox, but is apparently not completely unique.

Tor with letterboxing disabled: screen size is 1440x789x24 which is 1-in-100k!

So, basically, vanilla Firefox has a less-unique screen-size than tor browser on same machine, and letterboxing helps the tor browser a little bit but not as much as it should.

So, I'm thinking: panopticlick should publish stats on what are regular encountered values, including e.g. screen sizes.

The tor browser should prefer then use this data set to pick common values and combinations; e.g. for screen size, pick common sizes rather than rounding down to a hundred.

I'm also thinking the tor browser would be a lot more usable if the screen size was reported like vanilla Firefox; when letterboxing is disabled, Tor seemed to be claiming the window size was the screen size? And with my strange choice of window manager on an obscure OS, that made it unique.
