I forgot to reply to the list, so I re-added it

To further explain, in my setuptools replacement experiment I implement the develop command by generating a a wheel
Using a local version tag `+develop`,

Instead of the actual code, for each top-level it contains a shim python file that will load the real code from the editable location
However it will use pip to install that wheel and create scripts/exe files

In particular windows support for a full develop command is orders of magnitude more easy if one let's pip make the scripts(exe files)

I think it's very helpful for tool authors if pip has ways for them to avoid platform pitfalls like exe files

That way tool authors can completely avoid writing the target folders and
its possible to always run completely unprivileged builds

Thats an interesting idea, but wholly different to what 'develop' does
and is used for. My goal here is to only commit to new things where
the new thing is all of:
- a small amount of work
- meets existing use cases
- able to be put into pip/setuptools/wheel/etc now (rather than after
a bunch of other things are done)

I completely agree with the idea that develop as it stands has a
number of limitations, but there is no generic implementation
available for pip to reuse; there is no feature in pip that would do
what you want either; nor even a proof of concept. I think as such its
premature to PEPify it.

What could be done is to take the abstract build system work (which
*is* within reach for pip) and create a implementation with a new
schema version and whatever semantics you want around this new
developish thing, and write an incremental PEP (so you don't need any
of the PEP I've put up, just inherit from it and define your new thing
- and then we can kick the tires on it and see how its going to work
etc.

Note that what you describe 'generate a wheel with a local version' is
actually exactly what the 'wheel' command does as far as I can tell,
but I'm sure thats not what you have in mind - so please do expand on
the differences, in
paranoid-folk-make-sure-folk-cannot-misunderstand-style ;)
