Sorry if I'm out of the loop and there's some subtlety here that I'm
disregarding, but it doesn't appear that either of the issues you mention is a
actually problem with eggs. These are instead problems with how eggs get
installed by easy_install (which uses a .pth file to extend sys.path). It's
reasonable to put eggs on the PYTHONPATH manually (e.g.
sys.path.append('/path/to/some.egg')) instead of using easy_install to install them.
I don't think there would be any benefit to changing Python's import machinery
to deal with them; they are essentially just directories (or zipfiles) that
