Forks of important libraries in Debian (and adding patches) are likely to occur over time. There must be a sane way to keep track of these deviations and their eventual way back into upstream. This is true for both the Librem 5 phone and laptops.
This issue is meant to track these patched libraries until the changes are merged upstream. Any application that deviates (from the application available in Debian testing) can be linked as a dependency to this issue so that all deviations can be tracked in one place.
