I would like ODL to reconsider the point of YANGTOOLS-811.

I've been researching this a little, and it seems people from the RFC itself acknowledge that the RFC is unclear on this point:

https://www.ietf.org/mail-archive/web/netmod/current/msg17835.html

However, there are standardized YANG modules that are relying on the assumption that no if-feature is needed in the augment, see the following standardized models from BBF:

https://github.com/BroadbandForum/yang/blob/master/standard/interface/bbf-sub-interfaces.yang

https://github.com/BroadbandForum/yang/blob/master/standard/interface/bbf-sub-interface-tagging.yang

The first model contains at the end containers ingress-rewrite and egress-rewrite that are conditional under the feature tag-rewrites.   The second module contains an augment on these containers, without an if-feature statement.

It has also been brought to my attention that ConfD from Tail-F had provided a fix for this problem.    So it seems there is some kind of consensus out there that the if-feature statement is not needed in the augment.

That is why I request that ODL reconsiders this.
