I wonder if it'd be fruitful to ask the submitters of those bugs about
their experiences with the feature. Did they find it useful in finding
precedence problems in their code? Did they experience other problems
that they didn't report?
Reading the reports mentioned in those commits, it doesn't look like any
of them were actually using the feature -- they all seem to have come
across the problems by accidents of varying nature.
