so this default is a breaking change. If we want this to land in v16 then we should do Infinity and in v17 we can restrict the limits.

Why is that a breaking change? The behaviour is exactly the same as before. Infinity would lead to an infinite recursive loop.

@saihaj I think you may have misunderstood which depth this relates to - it's the ofType { ofType { ofType { ... } } } depth of the generated query. We couldn't set that to infinity.
