How would an optional, official parser be toxic?

You're wasting time doing runs with randoms, waiting for them to fill your pugs on farm parties and more, and them kicking them when they underperform or wipe you. If the content is hard enough, you're much better off not doing that and not hoping the randoms will be fixed by whatever half-ass measure the devs put out, and instead do it with a static and save PF for less demanding things.

PF was made for finding like-minded people to do content with, it's purposefully designed so you can control who gets in your party so you can have the smoothest run possible.
"Less demanding content" is what DF is for, as that's where you're actually not in control of who's in your party.
