My take on "loss of functionality" under 1.4.4 and 1.4.10 would be that if responsive design collapses functionality into, say, a hamburger menu, then there is no loss of functionality because it's still there, it just requires opening a menu to get to it. I assume there would be wide agreement on this but I may be wrong.
But how about this scenario? A media site has a search page that searches within all media and a separate search page in the books area of the site that only searches within books. On the books search page, the search filtering functionality disappears at lower screen widths but it is still available on the main search page at the lower width. Is this loss of functionality on the page but not on the site a "loss of functionality"?
