How about moving that warning from W=1 to W=2? Generally speaking
I'd expect W=1 warnings to be in a category of "it's generally better to
address this in the code, but we can't turn it on by default because the
output gets too noisy", as opposed to W=2 meaning "this sometimes
finds a real problem, but fixing the warning often makes code worse."
