What about a link to the email on lore?

This is the path of least resistance, but it's better to push back
on bad advice from AI.  Greg won't be offended.  And if he still
doesn't like after you push back then you can still do the min_t()
version.  Both versions are fine really, but I generally go with
the stricter one when it doesn't break anything that wasn't already
very broken.

Better to use umin() instead of min_t(), btw.
