--- Comment #12 from Mike Stump <mikestump at comcast dot net> --- Here is a case where we wish for actual feature testing of all the bits instead of the coarse grain, are we FSF gas 2.9 or later. Default should be things work nicely, and the feature testing should be to identify incomplete or broken things. Given the propensity for people to write a test, is this 2.x or later, that is a direct indication they wrote it wrong in the first place. Tests should always be 2.x or earlier to identify broken.
