I dont think that github.io allow content negotiation.  I think publishing
a webid to a static web page is a valid use case.  In fact, that's one of
my big motivations, here

I agree that it is obvious that every MUST is a barrier to adoption

I'd favour loosening the MUST requirement of content negotiation, for a
future version.  But there must be a path for those that use it today, to
continue to do so
