By default?  It would cause unpleasant horizontal movement of text,
e.g. when the line number changes.  Also, many variable-pitch fonts
have a very thin glyph for SPC, so different fields could appear as a
single field, another visual problem.

Of course, nothing prevents people from customizing the face to use
whatever font they like.

Could be a good idea.  Toolkit menu bars definitely use variable-pitch
fonts on most systems.

Emacs never assumes a face uses fixed-pitch font when it calculates
the various metrics.  So this cannot be a problem (barring bugs).
