Do you have a rough number how many tests warn about VLA currently ?
Must admit that I've very rarely look at the compilation output of
piglit. That combined the fact that new piglits get added
incrementally is a nice indication, imho, about one should handle
this.

Or in other words - it there are only a few of tests that need fixing,
there should be no problem with adding this. Otherwise it's a
different story.
