This is a good question. I guess the answer is that 'build requests' are
an implementation concept: users don't know the difference between a build
and a build request. So what the list of targets should show is targets
for: 

1. completed builds (succeeded or failed)
2. and failed build requests

This sounds good. Thank you.

This might be too much work, to be honest. I am happy if you can list the
top 5 targets per number of builds in decreasing order. When targets have
the same number of builds, we can choose which one to display in whatever
way is easiest (alphabetical order or some random thing: I am ok with
that).
