Well, it would be nice to be able to enable invariants on some
shipping "debug" versions of images in order to gather more data
without crashing the kernel.
Yes, two of my employers were more of "we want to get more debug
metrics, we have the spare cycles, but we can't deal with superfluous
panics".
It also allows us "non-architects" to slip in a debug image when we have
spare cpu without getting yelled at for "crashing the $foo".
