No, I'm just saying developers are, today, writing code that assumes 
little endian typed arrays.  Some are doing it deliberately, some are 
doing it because they don't know better, some are not doing it it all. 
But the net effect is that there is some code on the web.

This won't change the dynamic...

I don't think that's possible.

Yes, precisely.  The point of a spec is that it can be implemented and 
then the implementation would interoperate with other implementations. 
An implementation of the typed array spec that actually followed the 
spec and happened to run on big-endian hardware would not interoperate 
with other implementations and would not work with existing content.
