Re: SFS last call? was: Re: Proposed XMPP Extension: Emoji Markup

If SFS does get a seperate namespace to support this disposition value, 
then I'd like to incorporate it into my XEP and drop the SIMS 
compatibility entirely

I wouldn't like clients that support SIMS/regular SFS but not support 
Emoji Markup to misinterpret and display the attached emoji files as 
regular attachments (for the sake of UX/UI)
