Yep. Even just sharing code with any license is valuable. Much I have learned from reading an implementation of code I have never run even once. Solutions to tough problems are an under-recognized form of generosity.

This is a point where the lack of alignment between the free beer crowd and those they depend on is all too clear. The free beer enthusiast cannot imagine benefiting from anything other than a finished work. They are concerned about the efficient use of scarce development bandwidth without consciousness of why it is scarce or that it is not theirs to direct. They view solutions without a hot package cache as a form of waste, oblivious to how such solutions expedite the development of all other tools they depend on, commercial or free.
