Comment (by cypherpunks):

 > as you can see from my test

 Where is that test to be seen?

 As for the rest: I know what you explained. However it is still better to
 fix things to 1000x1000 because zooming in/out is user behavior and that
 *is* fingerprintable (and user behavior will become more and more a target
 for FP, with more powerful AI etc). So the idea here to reduce the
 possibility of the user to make inadvertent mistakes. One can still change
 the `zoom.*` settings in `about:config` but then it is supposed that one
 knows better what one is doing.
