Sorry if I wasn't clear:

http://bugs.gentoo.org/show_bug.cgi?id=472938#c1

"I think we should eventually get rid of the eselect module and load 
everything dynamically."

So what is left, after committing those posted diff's:

- Removal of bash-completion specific snippets from app-admin/eselect as 
it's no-op with the new way. This is more of a matter of cleanup after 
rest of the work is done. Although, if you want something more complex, 
then by all means...

- Postinstallation instructions to the new bash-completion to run qfile 
combination with emerge to re-emerge packages to move files to correct 
directory. Trivial to accomplish. Dunno why I didn't already put it to 
the diff.

As in, there is a complete transition plan in place far as I can see. I 
succesfully migrated already locally.
