This is also my use case. 8-/

This goes probably in a different direction of what has been implement
so far, but would it actually harm to enable the network-based
instance-data injection by default?  The advantage would be that it also
blocks these requests from leaking to untrusted parties, which could
then serve bogus data to compromise the virtual machine.
