I have a following project.

• Have 3 platforms to build.
• 2 of 3 (A, B) are major and I want to test automatically.
• 1 of 3 (C) are minor and I want not to test automatically as that platform is so slow and time-consuming. I want run tests for that platform only when I intend and operate manually.
• I want run them in a matrix project to know which artifacts are built from same versions.

If filtered platform-C with combination filter, I cannot run build for platform-C even I checked platform-C in matrix-combination-parameters.
(And it often causes NPE in views. SEE JENKINS-21889)

I want specify a default checks for matrix-combination-parameters.
It allows excluding platform-C usually, and enabling platform-C when needed.
