Just the NotImplementedError case: running build_wheel against a source tree is permitted to succeed in cases where build_sdist raises NotImplementedError, and in these cases, the result may *not* match what you would have gotten if the necessary inputs and tools for creating the sdist were available. > At the moment too much discussion is getting bogged > down with comments like "I think someone said that XXX needs this..." > > I'm *not* interested in trying to tie down "the correct behaviour" any > more tightly than this. Cool, we're on the same page then - the specific thing that was bothering me was the request to start articulating "permitted side effects" at the PEP level, and I don't think the PEP is the right place for that.
