I'm sorry, I'm confused now.  Let's go to your original 3 requests:

1) is for mode line, and is satisfied with min-width display spec
(which needs to be fixed, perhaps, see bug#52183).
2) is for pixel-resolution justification, and will be satisfied by a
new kind of display spec.
3) will should be per-buffer (or globally), and will be satisfied by a new
buffer-local variable.

Is something missing?
