commit 9bb6f1e11264fb075bfa70fa3684f10a32414594
Author: Lars-Dominik Braun <lars@6xq.net>
Date:   Wed Dec 1 14:28:06 2021 +0100

    guix: Remove accessibility.
    
    We cannot build speech-rule-engine from source and thus all dependents
    must be removed. This affects all a11y modules and menu items, which
    may try to load components.
