I've been sitting muling over this and here is what I'm wondering might
be a possible alternative?
Note that sanitzers tend to increase the rate of false positive
warnings, most notably those around @option{-Wmaybe-uninitialized}.
We recommend against combining @option{-Werror} and [the use of]
sanitzers.
Rationale for the second sentence: Disabling a warning that is off by
default confused my mental model (and maybe those of other readers). :-)
What do you think?
Gerald
