Note that Phoronix is being imprecise here and those hundreds are in fact data races (with no false positives), which are never okay.

This just isn’t true.

Here’s a concrete example - many JIT compilers use counters to work out when to compile a method. They allow data races in updates to the counters because performance is more important than correctness for them and the impact of a lost write is basically zero. It’s only a bug if you decide it’s a bug.
