Ah, so that's what -e is about. I can see that would be a problem, I'll try a normal install and see how that goes. > pip recognizes wheels and installs them itself. > https://github.com/dholth/pip/blob/develop/pip/req.py#L759 > > It doesn't yet +x scripts or update .dist-info/RECORD to keep track of > what it should uninstall. So pip remove won't work right on installed wheels?

But I'd expect a relatively long period when some developers use wheels, but a lot don't. During that period, converters would be essential to enable end users to start using wheels, and hence to start the process of pushing developers to provide wheels. But certainly converters are an interim measure. (Just an important one IMO).
