Honestly I don't think its a "way to tempt you" I think its just to add some narrative sense to the tadpole over you only having access to it in the grove. I do get that I also would like options to not have to use it aside then playing a Barbarian... I honest thought that if you succeeded the Arcana check on the console it was gonna be an alternative way to open it but no its just telling you what you already know this console is gonna open the pod.
Also note we don't know what happens if you keep using the tadpole yet.. as far as we know if you only go as far as the conversation in camp about " Do we keep using those powers or not" you might be perfectly fine.
