The bidi-mirrored property for all arrows is set to not mirrored
consistently. That should not be changed. Any change of bidi_mirrored
property creates a problem that implementation behavior is no longer
predictable - whereas predictability is the main reason for having this
property. (Not to long ago an attempt to fix an oversight in the
handling of some paired punctuation characters caused great stir,
because of that issue).
If the other orientation is needed for bidi, a proposal needs to be
submitted to add a set of corresponding RTL arrows. The justification
for adding the new characters would have to be based on consistent bidi
usage. (In my personal view, the need to encode these follows directly
from their bidi-mirrored property combined with the directionality
implied by the arrow shape).
There is a precedent for that, as the same was done for certain
mathematical arrows that by convention are used in one direction only.
