I think you need to consider this point and not just focus on DOMMatrix.  
What if WebGL or 2d canvas decide to expose DOMQuads or DOMPoints?

I didn't claim you would. I claim that WebGL is typically understood to be  
included in the "DOM" part of the Web platform, as is e.g. WebSocket. I  
don't have data to back it up though and I know that not everyone agree on  
this point.

Yes. I suggest it is not going to be a problem in practice.

The problem at this point is not really finding a better name (though  
personally I think all of those are worse because they are longer and so  
more annoying to type). The problem is that these names have shipped, so  
you need to convince the relevant browser vendors to change the name. If  
browsers do change the name, the spec will be updated to match what is
