I don't think so. That commit splits up the operation so to avoid
doing the entire operation in a single transaction, and the rationale
for this is sound. But the atomic work showed that it went to far,
because we can still batch up a fair amount of conversions. I think
the argument of allowing to batch up as many transactions as we allow
in an atomic write still makes perfect sense.
