It is the right list.

I'm not entirely sure.  There is a question about what upstream does,
and practice on Linux.   Arguably there should be some mk file in bash
that sets a variable, or perhaps in some mk/defaults/ place, and
packages should use that variable.

I see the point of conflicts with bash-completion package, but I don't
see how having the same name in different files (what would happen in
the same situation but a different place) is good either.

It seems that where completion files are installed should be someplace
bash looks by default, or we should decide that users should have to opt
into this.  But one decision, for all.
