I've been using guix since 0.15.0 and haven't seen it as much of an issue. Sure, channels will sometimes be out of sync with the latest commit but that's to be expected given that you're likely not following a version cut but rather the latest commit. It's easy enough to bump the package locally (inherit, etc) or contribute an update which solves this for everyone.

Needing channels for non-free is a feature as the system will be pure by default and can make progress towards fully reproducible builds for all packages rather than having several blessed non-free blobs around that drain maintainance time.

For the record, I use linux-nonfree, amdgpu, iwlwifi, firefox, and steam.
