It does effect testing and also releases unless we can tie the build logs to the
code stability. Filtering the build logs is possible with some scripting and
procmail but it is another task someone needs to do before it becomes useful.

Is it possible to determine from the build configuration which BSPs are
functionally equivalent? We could then minimise the build set and testing

Yes having the boards supported listed is a good thing.
