The thing is, the amount of residual chlorine needed to create a chlorophenol presence above detection threshold is far lower than the detection threshold of chlorine itself. Just because you can't smell it any more doesn't mean there's not more than enough residual chlorine to still cause chlorophenol problems.
I look at bleach as an absolute last resort. As in, an "oh sh*t, I've already started brewday and I don't have any Star San left" kind of thing, and even then, I've never reached the point of no return where I'd have to do that and couldn't postpone. Or, in the case of infection, I'll do a proper bleach bomb (which I've had to do once) to purge it from my gear. After which it gets rinsed with majorly hot water, cleaned with PBW, rinsed again, left out to air dry (where any residual chlorine should off-gas), and then I sanitize properly with Star San when I actually need to use it. And in the one time I did it, no subsequent infections some ~50 batches later, and no chlorophenol problem either.
Point being, bleach has its place but it's never a go-to for me.
