Wouldn't #!/use/bin/env eapi4 handle both (1) and (2)? You might have to 
eselect package-manager or something first if you want to use two PMs at 
once.

If a user marks the ebuild executable and does ./foo-x.y.ebuild, the 
eapi4 wrapper can decide what to do. Nothing at all, print larry the 
cow, or crash (what we do now) are all fine with me =)
