The person in the linked GitHub repo is not asking the maintainers to develop the feature. They are asking if the maintainers would like the issue author to develop the feature. That's what is particularly disgusting to me about this star-begging-bot.
They are asking the maintainers to take the time to evaluate and possibly shepherd a patch into the mainline. It may or may not work out in the end. Everything has a cost, not the least, opportunity cost.
