No.  It's not related.  I just want to point you to the warper that
does try to micro-optimize the horizontal positioning of a glyph.

Yes.

Correct.  It would be possible to adapt and re-use the warper code for
non-integer positioning.  Whether this is useful, beautiful, fast
enough, etc., etc., is another issue.
