Summary:
Ref T8424. I'm using Paste as a testbed application because Spaces make some degree of sense for it but it's also flat/simple.
This doesn't do anything interesting or useful and mostly just making the next (more interesting) diff smaller.
Test Plan:
- Ran `bin/storage upgrade -f`.
- Browsed pastes.
- Created a paste.
