I'm a fan of AGPL as well, but there's a point of possible confusion for GNU license variants I personally run in to and maybe others as well. It may be worth specifying which variant of the AGPL you are using, e.g. AGPL-3.0-only or AGPL-3.0-or-later.

That's fair. We use AGPLv3. I haven't seen any AGPL project that wasn't using v3, so we decided to keep it short for readability, but you bring up a very good point.
