The performance concern is real (3x slower for Object.is) but does it really matter in this case? It feels like this might be a micro-optimization too far.

It got better recently but those changes may not be in 6.3 yet. And yeah, I don't think Object.is() is going to be the expensive part here.

Sorry, I was thinking something more along the lines of:
// Format -0 as '-0'. A `value === -0` check won't distinguish 0 from -0. We don't really need to talk about the performance of it, IMHO.
