As I understand it, is FOAF currently served at that URI in a
form that is both machine-friendly and human-friendly (HTML
with RDF in-line). [1]  Are you simply saying that you will
continue to serve RDF-enhanced HTML by default, or are you
suggesting that administrators be allowed to decide to set
HTML as the default even if the HTML is not enhanced with RDF?

I suggest that this important point be clarified, perhaps
even in the requirements section itself.  If the default behavior
of RDF clients were to change, then the requirements with regard
to default behavior could also change (i.e. be relaxed).
