Id: Prevent deleting a feature with a Wikidata tag

[quincylvania]

If a feature has a wikidata tag, iD can assume that it is likely a non-trivial feature due to notability guidelines (Wikidata, Wikipedia). As an extra layer of protection against the accidental removal of important features, we should warn users if they delete these features .

See #5830 for upcoming UI improvements that will surface issues immediately as you edit.

Note that in normal editing it is common to delete features with mistagged wikidata tag (for example duplicate shop nodes that were mistakenly tagged with wikipedia rather brand:wikipedia).

You've linked to the Wikipedia guidelines, not the Wikidata ones.

And Wikidata has much lower ones: https://www.wikidata.org/wiki/Wikidata:Notability

@pnorman @matkoniecz Oops! Thanks for noticing, I updated the post with both links since iD couples Wikipedia and Wikidata rather closely.

The Wikidata policy allows

It refers to an instance of a clearly identifiable conceptual or material entity. The entity must be notable, in the sense that it can be described using serious and publicly available references

I could create wikidata entries for all the houses on my block.

This feature might still be worth it, but because of what Wikidata contains in practice, not it's notability policies.

Honestly I think we should just prevent users from deleting features with a wikidata tag - not just show them a warning.

@bhousel I'm fine with this assuming users can delete the feature after removing the wikidata tag. Like with editing the name.
