As with Zuo, can this be split into a separate patch?  If not, why does
it get mentioned here as something noteworthy rather than just being
part of the ChangeLog?

Prefer prepend over append.

Rather than skipping tests altogether, skip just the flaky ones.

This is a leftover from 8.6, but do the "FHS-like" installations
actually adhere to the FHS or just to the bit that says "opt means we
can do whatever we want 😎️"?

Is that something that needs be mentioned?

As always, Racket contains a gazillion of updated hashes that I will
simply trust you on until a build fails.
