[REQUEST] Make Jenkins.instance available in matrix combination filter

[Kinkie]

Hello,
I've found variations of this to be relatively FAQ.
Would it be possible to make Jenkins' instance available to Matrix
combination filters? This would unlock quite a bit of potential which
is currently not really tapped.

From my limited understading, adding

binding.setVariable("Jenkins", Jenkins.instance);
at
matrix-project-plugin/src/main/java/hudson/matrix/FilterScript.java:81
should do the trick..

Is anyone aware of any reason NOT to do this?

Thanks
