Is there any chance future CSS specification become more specific on this?

Currently Unicode TR #14 says that no line-breaking is allowed before the  
"]" character even if that character is a space. (You may have a  
line-break after a space but the rule for "]" prevents that.)

Is it likely that the behavior described in Unicode TR #14 becomes  
mandatory one day or will be clarified by a CSS specification (as it is  
also about presentation). And if so, in what direction would that go.

(Just phishing for hints here so we are not removing code we can add back  
later on.)

Kind regards,
