I may not be understanding you.  This is the WorldWide Web Consortium.  
It creates Web specs.  If it wasn't using Web technologies, we wouldn't 
be doing it here.

Are you saying that the charter doesn't make it clear this is about 
client side Web technology?

 From the Charter:

"The Web Near Field Communication Community Group will define an API for 
Web page scripts to use the..."

"The goal is to provide a Web NFC API that satisfies the most important 
use cases for NFC from Web pages."

"The scope of the Web Near Field Communications Community Group is 
limited to the development of APIs for Web page scripts"

"The APIs will be designed to permit execution in the Web browser 
context, using the security model of the Web."

"The CG will define a Web NFC API specification, suitable for use from 
Web Browsers."

If I'm understanding you, it seems you want to do something other than 
an NFC JavaScript API for Web Browsers and that you think that isn't 
useful or necessary.  Again, if I understand you, you would like a spec 
for discovery and message passing to native apps from Web pages and you 
think that would be a substitute for efforts like this group.

That would be a different group, not this one.   It would be one about 
registering and exchanging messages with native code.  There are other 
groups who could consider that: Web Applications Security WG, Web 
Applications WG, Trust & Permissions Community Group, Device API WG, or 
a new Community Group aimed at that particular topic.   This Community 
Group isn't for delivering general infrastructure like that.  It would 
be one of those groups or a separate group.
