I think your later comments about the use of .pth files solves the
issue for all four cases. We simply make reference in a .pth file in
one of the approved site locations. For example, in case two we would
write a .pth entry to site.USER_SITE. Sound about right?

Basically write the .pth entry for the build to a site (the standard
lib module) recognized location.

Ah, this case impacts the decision being made in issue 12279
( The decision is to write a RECORD
file or not. We wouldn't write a RECORD if you want to be able to
update without rerunning the develop command. But this would be
invalid based on PEP 376 guidelines. Please post your thoughts about
this in that issue.

The wiki page has been edited to note what the develop command will
write to the file system. I'll restate it here as well...

The develop command writes three pieces of information to the filesystem:
 1. It calls upon the build action(s) to build the package relative to
the package's root directory.
 2. It calls the [build|install]_distinfo action to write the
.dist-info metadata inside the build directory. (see also Issue 12279)
 3. It adds the build directory's path to a .pth file.

Thanks Carl
