A short question about the "Mailing list" option

In Options, under Reports, there's a "Mailing list" option.

I just want to know if this is _only_ used for mailed reports and new registrations notifications, or if it might ever be used for any other kinds of administrative mail.

(I'm wondering because if it is, I can safely remove myself from that list, and just let my moderators deal with reports and new users.)
