If I hear "/28 just for the infrastructure" I'd claim "they are doing
something wrong, in significant ways".
No network is so big that a /32 wouldn't be enough *for the infrastructure*
(4 billion /64 subnets), unless you start encoding stuff into network
prefixes that should not be there.
And no, people should not get /28s for (pure) "network numbers are hard"
reasons.
