No, I don't think that's 'OTT' as you call it !
You may not care about feedback from buyers, but I (and clearly others) do, as an indication of the sort of service offered as a seller.
Don't see any problem with that.
I'm not a kindergarten student, sitting up straight in the hope of getting a shiny sticker. That's neither the value nor the point of feedback.
If you are a seller yourself, you would know how much work goes into producing a good listing and making sure that you provide good follow-up service. If a buyer leaves you positive feedback, that makes some reference to that good service then that can I believe influence future buyers to be more inclined to buy your items.
And, yes, there will be a proportion of buyers who, like you say, are not entirely satisfied with the item they purchased but not to the extent of leaving less than pos. feedback. Its up to the individual seller to decide whether they want to follow-up, not just for the purposes of receiving feedback but also, less cynically to complete the process of providing good customer service, with a REAL interest in whether the buyer was happy. So be it, if this results in neutral or negative feedback.
