Taking risks?
Yes, and no.
Nope in the regards to they have not flushed out relics as well as they could have and still remain on a fairly rigid patch schedule.
Yes, in regard to the fact if they didn't take risks then they probably would not have gone for Island Sanctuary nor criterion/variant. Anything which follows outside of what they have historically done is a risk. Whether the risk in the long run for IS and the dungeons remains to be seen.
If they were interested in playing it safe they could just give the players exploratory content ad nauseum for eternity.
