I completely agree with your statement on the editor's role, and the second sentence as well.

This is the case where all agreed that the incompatibility caused by the difference is very subtle, almost unnoticeable, and will be completely gone when user use the right fonts.

The costs to implement vary by underlying architecture. For one architecture, option A is much cheaper, while for another architecture, it's opposite.

Having two options help both implementers, while we lose almost zero, compatibility in the real world isn't sacrificed, only tests might fail, and some does care passing tests.

That is why I'm asking, why John thinks we should remove option A.
