I found a minor outline issue with the ExtraLight master of 乞 (uni4E5E-CN). While this is a CN glyph, and I personally think it should be replaced with an unreleased JP glyph, I think it is more important to fix the outline anyway.
Left: Kozuka Gothic; Right: Source Han Sans
However, I also suspect that even the unreleased JP glyph may also have the same outline problems because Kozuka Gothic, the commercial font for which Source Han Sans derive from, also has this long-standing outline issue. This is the closeup of the same issue seen in Kozuka Gothic.
I'm not sure if Adobe will note this down if they plan to update Kozuka Gothic for any reason as it is on a completely different development cycle compared to Source Han Sans.
