Bart,

I'm ok with relaxing the checking.  If those interested in strict
compliance with the specification are not satisfied with this approach
then I think we would need to revisit RFC 35.

I would think we role this into 5.0 branch and we issue a 5.0.3 release
when we have enough fixes to justify it.  You can certainly deploy the changes
in your servers sooner than 5.0.3 is issued.
