[touch-events] Why don't Touch objects have offsetX and offsetY properties like MouseEvent does?

tremby has just created a new issue for 
https://github.com/w3c/touch-events:

== Why don't Touch objects have offsetX and offsetY properties like 
MouseEvent does? ==
The [W3C CSSOM View Module draft 
defines](https://drafts.csswg.org/cssom-view/#dom-mouseevent-offsetx) 
`offsetX` and `offsetY` properties on the `MouseEvent` interface.

These seem very useful to me, and I want to be able to get the same 
value during touch events. When transforms are involved, calculating 
the equivalent position is very difficult (see [my related Stack 
Overflow question](http://stackoverflow.com/q/36373114/496046)).

[`Touch` objects](https://w3c.github.io/touch-events/#idl-def-Touch) 
don't define an equivalent, as far as I can see.

Is there a reason for this?
