I believe the other working name this idea of ebuild code-reuse went under was "elibs". There was a partial GLEP written, enough that it was granted a number, but I forget that number off the top of my head. That said, I think a key problem here is the use of the word "eblit" has become poisoned for various reasons, and this makes the continued use of the term and its current implementation untenable. In general, the concept of code-sharing common blocks of logic between multiple ebuilds in a specific package directory that is not a top-level eclass is not entirely without merit. But the only way this idea can be realized in a suitable manner and be used by far more consumers than today's eblits are, is to either find and finish the old elibs GLEP or start one over from scratch, submit whatever needs submitting via patches to at least PMS and Portage, work through whatever processes are required for approval, and then deploy it in the next EAPI.
