+- Single location to clean up temporary directories.
+- allow a connection to a server to be maintained throughout the life, which would slightly shorten connections to Tika

+- supervisord isn't meant to run as PID 1, S6 is
+- s8 startup can be separated into independent units, with dependencies between them, which could slightly improve startup time
+ Initial work done in https://github.com/paperless-ngx/paperless-ngx/tree/feature-s6-overlay
+
+## Dropping ARMv7
+
+- No more need to custom build packages for the Docker image
+- Allows updating cryptography, scipy and probably more
+- Allows updating the Python version (to at least 3.10)
+
+## Migration Squashing
+
+- Faster initial migrations with squashed migrations
+- Would require moving much/all of the manual code migration functions into other files or another module
