Thanks for tracking it down. :)

I think of it like of Perl code without strict and warnings . They are recommended but not obligatory.

See also the definition of SHOULD:

> Key words for use in RFCs to Indicate Requirement Levels

  
3. SHOULD   This word, or the adjective "RECOMMENDED", mean that there
   may exist valid reasons in particular circumstances to ignore a
   particular item, but the full implications must be understood and
   carefully weighed before choosing a different course.
