Just a note that that is a typo: this is about a -bis version of RFC 7720, not 7701.

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".

I agree that <https://datatracker.ietf.org/doc/draft-hardaker-iab-rfc7720-bis/> should include a requirement that all RSOs support correctly responding to queries with the NSID EDNS0 option included. I also agree that there is no significant value to specifying a format, and that there may be a harm in fixing a format that might need to be changed in the future.
