Actually, you're right! I thought the proxy can nominate/decide that any other license can be used in the future (i.e. "licensed under GPLv3 or X" where I can chose X to be anything) but it seems that I was wrong. Re-reading more carefully (emphasis mine):

> If the Program specifies that a proxy can decide which future versions of the GNU Affero General Public License can be used, that proxy’s public statement of acceptance of a version permanently authorizes you to choose that version for the Program.

So FSF creates the future versions of a specific license the work is under (in this case AGPL) and the "founder" chooses whether to allow its usage or not. That sounds reasonable to me.

Thanks for the pushback!
