I've already expressed my opinion on this step in my response to
[00/11], but I'd say we take the patch as-is.  It is pretty much Meh
between moving some code that is only used once to a helper function
that is called from only one places, and not doing so at all.  Once
the code is written in one way, it is not worth the bandwidth and
brain cycles to replace it with a variant, the difference with which
is mostly irrelevant.

THanks.
