Contract upgrade wishlist

[sohkai]

To decrease noise, we use this issue to collect and curate potential improvements to the apps' underlying smart contracts. All other issues are closed and re-routed into here.

This is due to the long release cycles of smart contracts (requiring audits, long staging lifecycle, and opt-in upgrade path).
