I agree it is a very nice tool to have, but people overly rely on warp stabilizer.
The quote in this article "But we've been noticing them more and more even on big budget feature films." Shows that it is not good enough to not notice, the warping of perspective and motion blur artifacts when stabilized looks horrible.

When you have elements in the foreground and the background is moving you cant at all make stabilizing look any good
