But you are just scratching on the surface. As I noted long time ago,
the file itself is bash specific. To have bash in there makes sense as
the project was and is Bash focused. For other shells you end up
either maintaining your own codebase or constructing bash->YOUR_SHELL
translators.

If anything it makes sense to throw (part of) this into /etc/bash/,
which at least on Gentoo is the way to define systemwide data for
Bash.
