I'd set them to some roundup-related directory just in case that the
script or a program called from there dumps core.

This suggests that Debian's exim packages are flawed. Your upstream
author is not going to like this.

I'd suggest something like "However, the Debian Exim4 packages don't
allow pipes in alias files by default, and the maintainers have a
point in suggesting a different way to accomplish delivery to
roundup-mailgw".

Actually Debian Exim4 is maintained by a Team, and I am only a member.

That will only happen if the alias is still in place, which is not
necessary any more. If you remove the alias, the system_aliases router
will decline and anything will be fine.

I'd call that 010_roundup_macros

I'd call that 050_roundup (exim4-config is the custom for a file
belonging to the exim4-config package, which your file isn't)

Same thing here.

The list is only open to subscribers, so a link to the subscribe web
page would be a good idea.
