Pyang 2.6 error : node {::} is config false and not part of accessible tree

[AwTri]

Pyang 2.6.0/2.6.1 onwards we see that the yang files report warning for any when conditions set on a config false leaf as shown below. Why this is a warning for pyang, If we remove config false from the when condition leaf then the warning goes away. Also is there any way to mask this error.

NOTE: The feature supported may be config false based on different conditions and may not be configurable
