I am quite confident that there is no single magic set of operator
requirements that applies to all operators. I speculate that there
is a lot of commonality in operator requirements. Finding and focusing
on that commonality seems useful, if a bit of a challenge. My experience
so far is that enterprise operators often have a very different view
of the world than (for example) large core backbone operators.
I agree that there is not a single set of operator requirements. However,
it seams that the IETF did not do a good job in at least partly fulfil some
requirements of some operators (for config mgt).
