does glyph-mirroring make sense for things that don't already have a mirrored glyph at another codepoint?
It does. Contour integral needs to be "mirrored" but the direction of the arrow (circular) needs to be preserved. There are no mirrored code points, as the (partially) mirrored shape *only* exists in RTL display.
However, math font providers need to know about this and have the correct glyph available.
