It is not clear which issues remain open from this review.
The main issues seem to be:

   1) Put this functionality in yang-next instead of this document
    * The WG decided several times to go forward with this document

   2) When there is a yang-next, these extensions will not change or go away
    * This issue was not discussed as part of this draft. The WG should make
       these decisions if and when yang-next is a work item

   3) There needs to be machine-readable statements to define where a
structure can be used
    * The WG decided to just use description-stmt for this purpose

I do not know if this list is complete or correct.
That is for the WG Chairs to decide.

The 'structure' extension is basically a copy of container-stmt with some
stuff removed.
It is not a data node, rpc, or notification. Its use is
implementation-dependent.
A container-stmt is tightly coupled to protocols and datastores.  A
structure is
not coupled to anything.  There can be notifications and actions defined
nested within
a structure's data-def-stmts. (Who knows what this means - it is
implementation-specific.)

but it looks like the document is ready to advance based on this and prior
