The thought did cross my mind. However, I do not see any further
issues which need addressing. Nor do I have any visibility into what
issues may be caused by doing so. The only thing I know for sure is
that this patch fixes the compile error pertained to in the commit
message, and I'd like for this fix to be as atomic as possible, as
it's designed to be routed through the Stable/LTS trees.
