I guess you found them using your own code base? Maybe it would 
make sense to add one or more larger projects to the autotester, 
in addition to the unit tests. They don't necessarily need to be 
blocking, just a notice "hey, your PR broke this and that 
project" would surely be helpful to detect the breakages early on.
