Some of these are clear winners with the new approach.  The triple 
stacked item's old width is too narrow; you can almost not see the 
curvature.  And the thickness increases also seem much more appropriate 
overall.  At a minimum, the old thickness is too slender even for 
non-bold text.

But as with the alignment of chord alterations, this is just my personal 
assessment on visual consistency.  I agree we need the larger audience 
to chime in before changing default behavior.  Though, I will put forth 
that these very much are improvements and should be the expected output.

I do wonder, though, how to introduce these changes in a way that is 
compatible with folks who may have already tweaked things.  I doubt 
convert-ly would be able to do anything short of notifying folks that 
overrides might have changed effect.  Maybe the thing to do is introduce 
a boolean that inhibits smart scaling.  Users who want to compile old 
files and not manually re-tweak things can just set this boolean and 
everything works as it did before.  Folks working on new documents or 
updating old ones ignore the boolean and just leverage the new behavior.
