[cssm] MSPA + SMURF Constraints

CSSM Colleagues,

Following up from our teleconference earlier today I have confirmed that, for the DSN, MSPA is something that missions either allow or disallow for DSN scheduling but there is in fact no notion of "additional users" (which we have agreed to delete from the EnhancedConstraints class in any case). By default, a mission agrees to be put into an MSPA tracking configuration; they have the option to opt out of that.

So I think this tends to confirm, for the enhanced constraints, thinking about tracking configuration constraint parameters if we want to consider that. Note that this is a tracking configuration for service delivery and is not to be confused with a service configuration profile.  Another note is that in the case of DSN allowing the mission to be put into an MSPA tracking configuration is in some sense an anti-constraint in that it tends to maximize the opportunity for return services such as telemetry. Nonetheless, I am okay with considering this be all to be under the label of "constraints".

Best regards,
