Have they considered that the potential outcome of a failure to demonstrate
an ability and willingness to abide by the BRs and Mozilla policy could
include having their intermediate CA certificate distrusted?  Would that
create more damage than a "rushed revocation"?

That revocation would need to be "rushed" at all speaks volumes to Siemens'
unfamiliarity with the requirements under which they operate, or else their
unwillingness to abide by those requirements.  Revoking certificates within
24 hours of notification of misissuance is a requirement, and they should
know that, have planned for it, and have their systems and processes
designed in such a way as to be able to adhere to it.  If that were the
case, it would not be a "rushed" revocation and reissuance, but just
business as usual.
