Accepting that that is your position, and ostensibly a Microsoft position 
given the paper presented at the binary workshop, here is what many in the 
developer world see themselves as up against.

This is from Rob Relyea's blog on XAML:

So on the one hand, we have someone telling us the XML binary isn't a 
good idea for interop; on the other, we have a rich application client 
language developer telling us that is precisely what is intended.  Is 
this a fiefdom issue, or would we expect BAML to emerge as the MS 
choice for binary XML?  I'm not after MS's throat here; I simply am 
trying to show why it is so difficult to take the MS presentation 
at the binary workshop seriously.   In the rich client 3D world, 
we already take the need for the binary seriously.  It is simply 
a question of generality.  So far, all I see emerging as a consensus 
is 'the need depends on the application'.
