Oh absolutely it makes sense to have a standard, and being able to tell at a glance if something is a VM or physical machine is of value also. But dedicating 2/3s of the character budget to such a scheme is madness. If the prod-vm- prefix simply become pv-, then you'd at least be able to do pv-jenkins-01 again.

Anyway, all this was fine when we were on LDAP rather than Active Directory. So basically it's all Windows' fault.
