Thank you, i hope they will agree. :)

I'm not sure exactly what you mean. Isn't it the purpose of the 
setTransform method? 
(http://www.whatwg.org/specs/web-apps/current-work/#settransform, though 
it doesn't seem implemented by UAs yet).
Like ~getLastPointOfPath, it's just allowing to read values that are 
already in the UA's memory, so it shouldn't be too hard to implement.
I know applications can "emulate" it by overriding the other functions, 
or keeping track of it by themself, but it means significantly more work 
in this case.
