I am OK either way but this may be giving an early warning that a
typical mix of packages installed on a box will lead many people to
encounter this glitch in the real world, and we may need a more
seamless solution than a workaround.

Keeping this "fix" separate from the original commit that introduced
the issue would allow us more easily to refer real users who will be
hit by this glitch to it, telling them to do something similar to
their build environment.
