I am sorry but I do not agree with point (b) for the very simple fact that the average Windows user do not know how to compile the source code and might not even want to learn how to do it. The point is that since (if I am correct) the great majority of R users go Windows you would miss an important part of potential bug reports by requiring point (b) whereas (a) and (c) would suffice IMHO. Maybe if there were Win binaries of the prerelease version available some time before the release you would get much more feedback but I am just guessing.
