Design inconsistency with 羽 component, affecting 羽 (U+7FBD) (JP locale only)

Found a minor design inconsistency with 羽 (U+7FBD) ~and possibly 翻 (U+7FFB)~. The last pickup stroke does not touch the outer 𠃌 component in similar JP glyphs with the 羽 component (JIS90 forms shown), and yet for these two characters, the CN glyphs are being used for JP.

My suggestion for 羽 (U+7FBD) is to [replace the TW glyph with an unreleased JP glyph based on Kozuka Gothic](https://github.com/adobe-fonts/source-han-sans/issues/425) that can be mapped to JP, TW and HK, and keep the CN glyph only for the CN locale.

However, for 翻 (U+7FFB), in Kozuka Gothic, the right 羽 component has the last strokes touching the 𠃌 parts because it's space constrained; the only difference between it and the CN glyph is the design of the top-left 釆 component. Replacing the CN glyph with an unreleased JP glyph based on KozGo will not solve the design problem of 羽, only that the 釆 component, if the JP glyph was being used for JP and CN, could look a bit "inappropriate" for CN handwriting standards, so that's another matter not relevant to this design issue of the 羽 component.
