Just so you're aware, you've made some assumptions there:

(1) You've assumed that Top Secret is dealing with it correctly and in a way
that will work in all circumstances.  One key requirement is that there
never be I/O or serialization required to create a working security
environment (e.g., ACEE) to handle the RACROUTE REQUEST=AUTH for an OPERCMDS
check.  I don't know that they're not doing it correctly, but I also do not
know that they are in fact handling this mixed environment correctly,
either, with respect to this requirement.  And you might never know until
you hit one of the rare cases where this requirement really matters.

(1a) Also, and just for my own curiosity, have you tried routing a command
from a RACF system to a Top Secret system where the user does not have
appropriate authority to issue the command on the Top Secret system?  Does
it really fail in that case?  And does it have the user ID correct?  Also,
have you tried with commands from both MCS and EMCS consoles?

(2) You've assumed that Top Secret (and ACF2) are providing enough
information that RACF would be able to handle the request, if we still had a
way to ensure (1).  In at least some cases I know of, at least one of them
isn't providing any security information on the routed command.  

That's part of my curiosity in (1a), as I've heard a lot of people say "the
commands work" but I've never known if anyone has confirmed that there's any
security processing happening at all on the receiving system when the
security product isn't RACF.
