In article 
you write:

Plan B: figure out how to make your URLs short enough that your 
headers are under 998 characters. ...

Plan B is only feasible if the same person provides the URL _and_ writes the 
code to generate the
List-Unsubscribe header field (or any other list header field) for the 
corresponding message; not so if a
software library generates a message containing the value of a 
List-Unsubscribe (or other) header field
provided by a (third-party) user that, while otherwise syntactically valid, 
could exceed 998 characters in
length. ....

You lost me here.  Is there some force that requires you to pass giant
URLs to List-Unsubscribe?  If you want to interoperate, use reasonably
short URLs.  This should not be rocket science.
