This should be configured on-wiki, not in the server config of the wiki.

I disagree… it can still be overwritten in the Wiki, but we should be able to set a default for all Wikis in the config.

We provide the default config just like we provide the default Lua modules. This shouldn't be different.

Sure, but that shouldn't be hardcoded in the extension as the extension is supposed to be Wikidata-agnostic (it only knows about Wikibase).

We will have a number of property lists that will depend on Wikidata. The other ones are for example the ranking of properties and the blacklist of properties. We need a sane and easily editable (by the editors) way to let them change and maintain it.

I don't think making this completely independent of Wikidata is necessary. Easy editability by Wikipedia editors is more important.
