True, but since I'm not the one implementing it, the best I can do is
take the route of changing policy first. I think this is the best method
is this case, though, since the change will affect numerous webserver

They can. I've done this myself. But then none of the Debian packages
that rely upon <webroot>/cgi-bin will work. The purpose of the change
isn't to alter the webserver packages, but rather the packages that make
use of them so they will not conflict with what the webmasters want to do.

This has how I've done my site, but it's a pain. Also, many webmasters
run virtual websites and thus such symlinks would have to be done (or not
done) for each webspace and that's not something can be easily automated.

That's up to the webmaster. If they are using Debian packages from within
their own pages, they can create a symlink exactly as you describe above.
However, not creating the symlink won't affect those pages completely
controled by other packages, like dwww. By splitting thing, the webmasters
have the choice.

That's an excellent point. A webmaster could change <webroot>/cgi-lib
to point to ~www-data/cgi-lib and then only create symlinks for those
scripts he wants enabled for that (virtual?) host. For the most part,
though, people that install a web-based package want it to be available
so I think that is a good default.

They can. Apache needs a "FollowSymlinks" option enabled.
