I work badly with people that pronounce professionalism as a form of conduct too much to be honest. That said, my professional conduct on the technical side is always to vendor that shit if the project is of a nature that allows doing so (mostly restricted to proprietary software). Even for builds. There are harsh disadvantages with doing that if maintenance is disregarded, but these are problems you can tackle yourself instead of being dependent on third party tools working.

The sheer numbers of users of NPM says that this can happen from time to time and the stability they are providing is nothing other than exceptional.

Otherwise professional conduct mainly comes down to creating an atmosphere of noncommittal distance to deal with difficult personalities. I think being subjected to it for too long should disintegrate any personality, because it is completely unnatural. Hard to imagine people longing for more of that.
