One small change is less risky than one large change, but
it's unclear to me that the total number of broken builds (downtime)
can be reduced by breaking a 10-file patch into 10 1-file patches.

If there are K errors, they will break builds K times
if we discover and fix them one by one.
The hope is to find error before submitting file #2 from the
regression of submitted file #1. But it seems more likely
to discover both errors in #1 and #2 when they are submitted together
and then reverted and fixed together.
