Well - as Paul implies, there are 2 distinct changes being proposed, but 
in 2 different environments.

For an installed Python:  If it has to move, it may as well move to 
somewhere consistent with other platforms.  IOW, moving to "bin" seems 
preferable to moving to Scripts.  My initial objection was to moving it 
at all in an installed Python.

For a virtual env, we are talking about moving it *from* Scripts to bin, 
which may cause some people different problems.  However, that isn't the 
concern I was expressing and I'd hate to see virtual envs remain 
inconsistent with an installed Python after this effort.

So I'm assuming that:
* The executable (and DLL) are moved to a "bin" directory in an 
installed Python.
* distutils etc will change to install all "scripts" (or executables 
generated from scripts) into that same directory.  IOW, "Scripts" would die.
* A virtual-env would have an almost identical layout to an installed 
Python.

Cheers,
