What do you want to do that would significantly benefit from such
features?  For the most part, we want to keep individual piglit tests
small, and generally small programs don't see much benefit from such
features.

One of the goals (alas, not requirements) of a piglit test is that
someone debugging a driver failure in that test should be able to
completely understand what the test is doing in a minute or two.
