I doubt this would be a can of worms, but yes this may introduce
regressions. Based on my experiments, these should be very rare, so the
downside is pretty small and in the long run it's probably worthwhile.
This said, the upside is also pretty small, so you have to look fairly
far into the future before such a change becomes worthwhile.
