Oh, the reason I was thinking of using TGT tickets was related to my comment
at the end about deleting the synthetic principal to do fencing.

I was thinking of a TGT with a fairly long lifetime (as long as layouts need
to be valid) and a service ticket with a short lifetime, so that the client keeps
using the TGT to get a new service ticket/GSS-context.
Then, this would fail when the synthetic principal is deleted in the KDC.
(I don't think that renewable tickets are needed, that was a brain fart on my part.)
