[Commentor] LC-266 Ian Jacobs [Working Group decision] We have reworded this to read "not to exclude access from any particular class of device, except where this is necessary because of device limitations." [Commentor reply] yes [Comment] 
The document says "as far as is possible." When is it not possible? I think you can safely say that it is considered "best practice not to exclude access." You don't have to add disclaimers. If there are specific cases that you are thinking of (e.g., there may be privacy or security reasons), please call them out rather than say "as far as possible." I make similar comments below.
