Both packages have 2 lint warnings which I believe are acceptable. Each has a lint error for the description line being too long, but the description follows the advice in the "Synopses and Descriptions" section of the manual, and I can't break it into multiple lines because it must be a string literal. The other warning is that the TLS certificate of spacemacs.org, the package's main website, does not match that of github.com, where the code is hosted.
Below is the output of `guix format-patch -1`. Let me know if any additional work is needed.

+Spacemacs uses ~/.emacs.d in 2 ways: to store the code implementing the spacemacs framework and to track state. When we tell spacemacs that it lives in the store it tries to use the store location to track state as well. This patch adds a new variable, spacemacs-data-directory, for keeping track of state. This defaults to spacemacs-start-directory for upstream compatibility.

Mnemonics mean that key bindings use letters that stand for the action they take, making the easier to remember. Discoverability means that help is displayed when partial keybindings are entered, and prepared configuration units are searchable. Consistency means that bindings for different use-cases (eg, different programming languages) use the same keybindings for similar actions. And crowd-configuration means that the spacemacs community collaborates to provide the best default experience for new and expert users alike.")
