Make WikibaseRequestHelper public

So that multiple entities can be refreshed at once (and ids resolved from site links).

The BuildQueryOptions method would also be useful for WikiSite.InvokeMediaWikiApiAsync users,

Did you mean EntityExtensions.RefreshAsync extension methods? You can refresh a batch of entities with this method.

The BuildQueryOptions method would also be useful for WikiSite.InvokeMediaWikiApiAsync users,

I'd recommend you to write your own logic for building such query parameters as I don't want to make guarantee that the behavior of BuildQueryOptions will keep consistent throughout the updates.

Or could you please explain a bit more why you may reuse most of the logic in BuildQueryOptions? Are you trying to fetch properties that does not (yet) exist in EntityQueryOptions?

Exactly like that.

As for BuildQueryOptions, I was trying to recreate RefreshAsync to get access to actual server responses.

If you are re-creating RefreshAsync, you'd better re-write all the logic by yourself.

If by "actual server responses" you meant there is some network fiddling needed, probably you'd want to intercept WikiClient in order to achieve this.
