In the case of email header fields, it was recognized that duplicates *did* 
occur (rarely) in the wild, and that the primary need was to be able to 
document what did exist in order that designers could avoid them.  Local 
experiments sometimes escape and become global de-facto standards.  By 
prohibiting provisional registration of duplicates they would be forced out 
of sight, with no clear way for designers of new fields to avoid duplicates.
