What's wrong with "there is content using this, so we support it for  
backward compatibility" as an argument? Whether it makes sense in a given  
case is about judgement, but prima facie it seems like a rational  
explanation for not following the "should" statements' recommendations.

Paving cowpaths and solving real problems and all that.

In any event, it seems that the statements that "everything not permitted  
is forbidden" don't seem to reflect what the actual document has said for  
the last seven years. I'm not sure this discussion has been very  
productive, beyond clarifying that :(
