Your requirements are from the perspective of people who view/use the code. I'd argue there are many benefits for the coder by releasing code including getting feedback from the community on aspects that could be improved or changed. This learning aspect is important as well

that may be true, but is it worth the time of the community to critique code that offers them nothing in return?

one might argue that the decision as to whether code is worth reviewing is up to the individual, and i would agree. but i would also argue that it's the responsibility of the author to decide whether or not the submission of that code in a public forum will generate more light or more heat, and filter such submissions accordingly.
