No-one that I know of - this is the first time the subject has been
mentioned publically in OpenMath.

Having only looked briefly at the schema papers, I cannot see any
burning necessity for OpenMath to embrace them now. As Angel says,
tool support will increase, and it may be possible to start with an
automatic translation of the DTD.
