There's a reason shops have surveys at the end of the receipt, because they take what people say into account. If it's something that can't be fixed easily enough or doesn't warrant a fix then they'll make that decision. That's what they did with Bahamut's size, that's what they did with guass barrel and why other things have on/off options.
If I have an issue with that sound I would like to turn it off when it's something that's played a lot. I also feel like I shouldn't have to turn off all other player character sounds to do it. In fact they've constantly shown that they support even the smaller group of player's who want certain things done for rping or just because they found it annoying. I'll use /groundsit as another example.
I'm not saying they better add this, I'm not demanding it, but I'm for sure not going to let someone tell me that I can't even put up the problem that I'm having for discussion because they decided they didn't think it was a problem.
