You can also just do a crayon license. "All rights reserved, noncommercial use allowed." Nobody's stopping you. If and when Debian wants to ship your package, ask them for proper legal advice about changing it, they have lawyers.
I'm not sure there's a lot of fear of GPLv3 out there. Linus just didn't want to adopt it for Linux.
AGPL is a different matter because companies are unsure of the boundaries between their own proprietary code and any AGPL code they're using.
