How would an optional, official parser be toxic?

I honestly don't see why an official self-only parser would be a problem, you couldn't really use it against others, and you'd know what your numbers are, so you could improve

My guess is there will be "must have in-game parse of XXX or high. Show screenshot of proof or kick" which...sure, comes down to gameplay preferences, but people are technically already doing that with their not-technically-allowed parsing methods. To reiterate a previous post, were we to get one in game, I would hope that it would be something akin to the Duty Recorder where all members have to opt in, so there's a clear concent among people who want to be parsed (like those who want to improve/handle difficult raid tiers) and those who are fine as long as things get done without issues (like your duty roulettes and other casual dungeons).
