I have seen Eli and others request several times that C code remain
indented with a mixture of tabs and spaces, aka the default value of
indent-tabs-mode.  By comparison, indent-tabs-mode is set to nil for
Elisp code, although not all contributors follows this convention.

So by "existing policy" I was referring both to our C convention, and
the fact that indent-tabs-mode defaults to t anyway.  Making this
explicit in .dir-locals.el is for the benefit of people like myself who
change the default value of indent-tabs-mode in their config.

I originally included the .dir-locals.el change as part of my patch for
that bug #, but was asked to commit it separately.  I try to always link
to any relevant discussion/review/approval in my patches for posterity.
