The distinction is between those glyphs that refer to "scriptsize" forms (e.g. asup refers to ss.a), and the ones that are scaled versions of full-sized glyphs.  The latter appear rather light.

Not all affected letters have been fixed.

Oh well couldn't stop myself.
I did all the superscript letters in "Combininng Diacritical Marks", in regular and oblique.  (Never did make script-size letters in bold)
In SVN.

No, none of these is particularly important.

Yes David, again--you do have a keen eye.

What you are seeing is a result of a technical measure that hasn't been completely finishde.  That is, to make a set of "small caps" glyphs, whose heights are like that of capitals, but have the same  stem width as the full-sized letters.

The "appropriate width" letters are scaled down from thos small caps letters, while the others were (probably) simply scaled down from full-sized letters.

This will be very time-consuming to fix.  Is any of these a game-stopper?

Many modifier letters are too light in FreeMono. For example, compare U+1D51 MODIFIER LETTER SMALL ENG to U+207F SUPERSCRIPT LATIN SMALL LETTER N. The pattern seems to be that modifier letters based on ASCII letters (e.g. ⟨ᵃ⟩) and their rotated forms (e.g. ⟨ᵄ⟩) have appropriate weights, whereas all others (e.g. ⟨ʶ⟩, ⟨ჼ⟩, ⟨ᵝ⟩, ⟨ꟸ⟩) are too light. Moreover, three ASCII-based modifier letters are too light too: ⟨ˡ⟩, ⟨ˢ⟩, and ⟨ˣ⟩.

“Too light” specifically means that the strokes are about two thirds the width of the heavier modifier letter glyphs.

For this bug report, “modifier letter” refers only to superscript and subscript letters. Other modifier letters like ⟨ː⟩ are fine.
