The tests can't generically assume a lot about what the BSP needs.
In general, the tests are better off saying "all" since with 100 BSPs,
you might not have the same requirements across all BSPs.  For
a user application, you should have a small enough BSP set that
you can make a better statement about what is really required.

For size purpose, MANAGERS=all is often better anyway.
