The proposed changes in the comments below create significiant

worldwide for several years.

The result of making any of these changes would be instability and
inconsistency between implementations, creating an environment in which
nobody can use these extensions because there is no reliable behavior.

This document and its protocol are not new.  Both have been around for
many years, and their publication was delayed unreasonably, due to (what
is now generally recognized to have been) a false belief that
internationalization had to be solved first.

Any of these changes would add further multi-year delay to this protocol
and specification.  Some of these involve considerable complexity which
will require long discussion to hammer down.

I recommend that these issues be punted to future work in new standards.

+1 - as written both SORT and THREAD can be easily extended with new 
behaviors as needed.

The current document describes what has been deployed to date. Whilst there 
has been much chatter in the past about defining new e.g. thread methods, 
nothing has come from any of that. So either people are happy with what is 
there now, or no one really cares that much about either of these because 
most clients in use do offline sort/thread anyhow.
