No. I am against deviating from the benign data race template, for either current or future changes,
without the clearly overwhelming benefit of doing so. We have enough bugs as it is to risk exposing
more bugs for the cases where the benefit is non-compelling. Therefore, my concern would be
alleviated if we don't do this change at all.
