Sure, I can slap a managed CPE on site if I don't already have one and provide overlay encryption - but that doesn't stop a rogue engineer on my side from capturing data before it's encrypted. If what you're concerned about is fibre taps, or security flaws in the MPLS traffic-segregation model or implementation, that helps. If you don't want to trust me as a service provider not to sniff your traffic in the middle, having me encrypt it at the edge really doesn't help - you need to encrypt it yourself, or have a different third-party that you do trust do the encryption.

Agreed.
There was a time when the use-case for MACSec was to move banks away
from running their own DWDM/FC networks, and letting operators do it.
I'm yet to find a bank willing to do this.
Maybe I'm not paying enough attention.
