- Remove 'blacklist' + provide results on the edges of local auths
- Detect and solve certain classes of errors in council data
- Simplify edge case handling
- Improve performance: everything is a PK lookup
- Reason about performance consistently: performance will be roughly the same with 1% coverage and 100% coverage (using denormalised model)
- Know that we are not making incorrect assumptions about postcodes based on incomplete data
- Certain classes of error become much easier to detect (e.g: polling district doesn't quite clip to local auth boundary)
- Gets you towards a case where the user journey can be "start typing your address..."
- If the council supplies an ambiguous address but it has a UPRN attached, we can discard less ambiguous data and achieve better coverage rates
- We could query EE by point to avoid 'fuzzy edges'
