People could ask "why not GUA"? The answer is: it is difficult to get yet another /28 GUA from RIR just for the infrastructure. /28 goal has the technical roots by itself. It is the sort of technical solution.
RIR typically give out the space that one really needs.
If you can justify it, you will get it.
If you cannot justify it, you likely do not need it.
As a LIR can get a IPv6 /29 per default (and then likely never have to ask again).... I would be very surprised if one is a large entity that one cannot receive an extra /28.
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.
Full ack on that. Hence why I mentioned "if you can justify it" :) Greets, Jeroen
