Nit: Consider a comment about why we have this.

Are your needs for this restricted to, say, debugging or unittests?  In those
cases we can further limit access here.

Added a comment.

Basically I pulled this out of another CL as my new team mates complained that
my CLs were too big. The uses I have are in DLOG statements and debugging.
