Well, honestly, YANG 1.1, while compatible when viewed from the perspective of a client processing XML, has a different metamodel than YANG 1.0. One example for all: YANG 1.0 metamodel did not require multiple inheritence anywhere, whereas YANG 1.1 requires it to deal with 'base' being '0..n' instead of '0..1'. While it is a relatively simple change on the surface, making it happen in a software ecosystem (with API stability guarantees, release cycles, etc.) does frustrate users even in presence of non-lazy authors (who also get frustrated)...
