But that's not really what I find objectionable.  There's no need to
make EAPI so special that it alters the file extension.  If EAPI is
accessible as part of the file or in metadata.xml, e.g., it still serves
this purpose well, and that info is exposed at the right level.

I would not suggest byte-level methods, no - these files are not binary.
 There are simple ways to parse text files to find the EAPI.  If it is
in the ebuild, putting it in the header (out-of-band) works.  If it is
in metadata, simply parsing XML works.
