If it's not expected to be a problem, then there shouldn't be any difficulty meeting the requirement, should there?

I think the concern arises because there is not yet even *one* complete implementation that meets *all* of the necessary requirements (including, for example, good behaviour when encountering an RFC-3168 AQM).  This points to the likely difficulty of a second implementer's task in replicating the feat.
