It would be nice to have similar properties IDs in wikidata test and wikidata so people who develop bots can easily do it transparently on Wikidata test without requirement to remap the properties ids.
Crazy idea:
- Completely remove Wikidata test database tables (it's going to be fun!) or at least all the properties
- Import all the properties from Wikidata
It doesn't have to completely sync with wikidata - but even if we do it once a month it is probably enough (usually "important" or "useful" properties are with lower IDs, except when new data types are introduced)
