I'm curious about this possibility. One thing that would ease experimentation in this area, and which has certainly been discussed elsewhere in this thread, would be if there was a clearly defined set of setuptools facilities that are missing from distutils, and which the "modern infrastructure" relies on. Off the top of my head, the following items would definitely be needed: 1. An extension to the install command to supply a list of the installed files (the --record feature of setuptools) 2. A bdist_wheel command 3. Updates to the install (or maybe bdist_egg) commands to emit Metadata 2.0 and dist-info metadata 4. An install_scripts command that created script wrappers from metadata (may not be needed if the only supported route to install is via wheels) To be honest, these extensions do seem relatively achievable. But I don't know if they are complete - can the advocates of setuptools clarify what facilities of setuptools are needed beyond these (with an indication of where they are used in the build toolchain). There are other features of setuptools that I can see would be relevant (for instance, version parsing and requirement checking) but these seem to me to be more in the nature of utility library features than distutils enhancements per se. I'd fully expect that such code could easily be extracted from setuptools (indeed, it may be that all of that code is isolated in pkg_resources already) without needing any of the distutils monkeypatching/extensions. It may be that such an approach is reinventing the existing wheel that is setuptools, and indeed it may never go anywhere - but it is an interesting alternative train of thought. Paul
