Dear Kent, Andy and Alex,

I think Alex statement 
https://mailarchive.ietf.org/arch/msg/netconf/5Yaiom0B0lDTeSPOvgNfPIEFvBw/, 
Andy's feedback and guidelines in 
https://datatracker.ietf.org/doc/html/rfc8407#section-4.4 resp. 
https://datatracker.ietf.org/doc/html/draft-ietf-netmod-rfc8407bis-15#section-4.4
 makes perfectly sense and I don't see why we should do else. As an author, I 
suggest to add in section 4 of draft-ietf-netmod-rfc8407bis based on the 
conclusion of this discussion guidelines on reusable YANG groupings.

Best wishes
Thomas

Hi Andy,

The main purpose for YANG defaults is ease of use.
If there are less things to configure then the device is easier to use.
Without a default port then this parameter becomes mandatory to configure.

Alex is trying to maximize lazy binding.  That is, as a general statement,  
unless 100% sure, groupings should never specify the “default” or “mandatory” 
statements, leaving it to terminal “uses” statements to specify.   His comment 
raises to the level of something that could be an addition to rfc8407bis.

Thoughts?

Kent
