Yes, I saw you were talking about the subsystem, but I think this is highly related to the whole picture. The OS/2 subsystem in released NT was neither a critical component, nor was it actually interesting for MS that it became too good. However, it was possible at all, for a lot of reasons, because NT was originally intended to be NT OS/2.
