My direct peering is within my control, the traffic has to follow basically the
same path internally to Internet and IXP. Internet path is definitely
variable. IXP path is definitely fixed. It's already there, just needed to
know what Microsoft provided (if anyone knew). Actually, a MS peering engineer
answered the question for me privately.
My marketing people aren't terribly concerned with security, that wasn't the
issue. The issue was shorter path/better performance. I'm still not clear if
it's public or private Azure that the customer is trying to access.

As a practical matter, if they're using the answer for a security baseline,
they're doing it wrong - they should be planning that based on the assumption
that their traffic *will* ride the rails of the commodity Internet (due to
outages or whatever).
Similarly, if they're looking at it for performance/latency, they need to
fix their assumptions - your direct peering can be slow and congested, while
there's actually a longer but faster path through someplace else....
