Open source developers face a licensing dilemma with GPL-3.0-only versus GPL-3.0-or-later approaches. The former locks projects at version 3.0, while the latter allows anyone to upgrade to newer versions. Section 14 of the GNU Affero GPL offers a middle path through proxy delegation, solving the problem of gaining consensus from all copyright holders while maintaining control over license evolution.

The proxy delegation mechanism allows projects to remain "GPL-3.0-only" in practice while enabling future upgrades. By designating a specific person as the proxy, projects gain flexibility without requiring unanimous consent from contributors. This approach maintains the spirit of copyleft while addressing practical challenges of coordinating multiple copyright holders in distributed development.

This technical solution represents an elegant workaround to a persistent licensing challenge. Rather than choosing between rigidity and unpredictability, developers can now maintain stability while preserving upgrade paths. The approach leverages existing legal language in the GPL to create a hybrid model that balances control with adaptability.
