I don't disagree.

yeah, but...  putting something new in, only to pull it later, is a bad
paradigm for adding new mgmt interfaces. Believe me, I've felt users pain in
the reverse flow : driver-specific stuff that then has to migrate to upstream
interfaces, complicated by different pull points by different distros. You can
migrate a management interface, but can you really remove/pull one out ?

Isn't it better to let the lack of an interface give motivation to create
the "right" interface, once the "right way" is determined - which is what I
thought we were discussing ?    or is this simply that there is no motivation
until something exists, that people don't like, thus they become motivated ?
