- The current `max_code_size` on Polkadot is 10 MiB, but it should be 3 MiB.
- This is causing a problem because the `consistency_check` function expects a smaller size.
- The proposal suggests changing `max_code_size` back to 3 MiB.
- This change is needed to fix the `consistency_check` function.
- Parachain teams should ensure their runtime upgrades are under 3 MiB.
- Most parachains currently have runtime upgrades under 3 MiB, so no major issues are expected.
