Some do I'm sure. However if we see something unexpected and it turns out to be true that means our ideas of physics are fundamentally wrong. While it is long term good to correct our understanding, in the mean time a lot of the real world depends on us being right, and so until we correct the theory who knows what will work. I'd hate to find our margin of safety on nuclear bombs was too small and it is only luck that they haven't all blown up in their silos over the years.
