Currently all the existing RSOs do support NSID and return some value (see below).   Since they all do, it seems like an easy jump to put the requirement into RFC7701bis.  But there is also a question of what value should be reported; I'd think it should be a fairly simple statement that doesn't prescribe an explicit format, but rather should say something generic like "indicates a unique identifier for a given deployed instance”.

How about this:

MUST implement the Name Server Identifier (NSID) Option [RFC 5001]
and SHOULD set the NSID payload to a string that conveys the server's
geographic location.
