How would an optional, official parser be toxic?

[JunseiKei]

For god’s sake, stop asking for parser.

This gets asked far too often. The answer that keeps coming back is a very firm "No." Perhaps joking or not, Yoshida started to walk out on yet-another-Parser-please question. To the point that he said, "No, we will not make an official parser, even if it only tracks the individual. We know it will be broken, re-coded or otherwise re-worked by the community to display everyone. Please stop asking."

As for the topic, "how would a parser be toxic?" Before SE pushed the 'don't ask, don't tell' mentality of parsers, people were kicking under performing players for not pulling arbitrary numbers in their parties. This is probably what SE is trying to avoid, because if they make, or otherwise acknowledge, an allowance of the tool, people will be excluded for ... reasons ... on a game they pay a membership for. It will then be SE's problem officially. Right now, it's more of a 'don't want bad players, don't run with random players' - like any other MMO or multiplayer game.
