I agree using this list would not be a good idea and I would suggest
using a team email address on tracker.debian.org instead of a new
mailing list.
Since we already have a team on Tracker [1] this means all we would have to do is change the Maintainer address listed there from
pkg-games-devel@lists.alioth.debian.org to
team+pkg-games@tracker.debian.org. To prevent breakage during the transition, we could institute a policy that all new Games Team uploads add
team+pkg-games@tracker.debian.org to the d/control Uploaders field. Once all packages have that update, we could switch the Maintainer address in Tracker and then gradually replace the old address with the new one in the d/control Maintainer field as we make updates.
This obviously isn't an urgent need but if we start slowly now then this should be a fairly easy transition.
Anyone have ideas on a better approach?
