I'd be somewhat concerned though about Guix sooner than later not running smoothly on Guile 2.0 due to the vast majority of users using and testing with Guile 2.2 rather than Guile 2.0. There was some breaking changes in 2.2, and it seems like wanting to support both might lead to code complexity or restraint that would otherwise allow simplifications and clean-ups of the code base. Also, nothing is stopping security minded individuals from building Guile 2.2 from sources, so the argument about security seems a bit moot to me. But I will leave it to the Guix maintainers to decide what works best for minimizing their load :) Thanks again for sharing your thoughts, Maxim
