Use case:
- a shared low-level module defines a feature and
defines a grouping with an if-feature with it.
- the grouping is used by various higher-level modules.
- in some uses of the grouping, the feature is desired,
and in others not.
- current yang-library enables the feature globally
(per-datastore), which prevents local variations
Possible workaround:
- each higher-level module can redeclare the feature
and augment in its own if-feature statements.
- this seems heavy and probably doesn't scale well.
- e.g., servers would support all the low-level
features (or perhaps the subset needed via some
cascading dependency tree), and then selectively
support the higher-level features.
Thoughts?
