You don't take feature development lightly: each feature will be discussed and polished patiently within your team. And then you release it, for free.
Then semi-random people from the internet want to continue the discussions that were settled privately long ago, while also demonstrating this entitlement.
I guess that can be a maddening, constant stream of noise. One that cannot be dismissed harshly - you may be an expert, but definitely don't want to scare people off.
Kudos to the Clojure core team for resisting the stream in a classy, illuminating manner.
