+Recommends: %{name}-bash-completion

I'd not do that. Rather make it the other way by supplementing bash and %{name} together, from the bash-completion package.

so, like this:

%package bash-completion
Summary: …
Group: …
Requires: %{name} = %{version}
Requires: bash-completiong
Supplements: packageand(bash-completion:%{name})

This will do basically the same, with the advantage that the bash-compltion sub-package will only be triggered for auto-install if bash-completion is already installed on the system (or triggered for installation).
