Unfortunately, another issue with the current CVS version was a
blocker for my particular case, so I switched back to an older
version a couple of minutes ago.  Hmpf.  My current Emacs version
(which displays the sub- and superscripts with correct widths) says

     dejavu sans mono:pixelsize=17:foundry=unknown:weight=regular:slant=normal:width=normal (#x6A6)

It's the same here.  However, the sub/superscripts used to work
until recently, see above.

If the adjustment of glyphs from different fonts is not feasible, I
must and can live with it.  But it's certainly a useful thing to
have in my opinion.

Tschö,
