Right now, a lot of story progression is tied to the long rest mechanic. To experience the story fully, of all companions, you will have to rest a lot, more than necessary for mere survival in EA.
But from the perspective of the characters, they would want to do everything in their power to do encounters quickly, and with as few rests as possible, because there is always the risk of turning into a mindflayer.
So the goal from the players perspective should be to take as few rests as is possible, basically as a self inflicted difficulty setting, because otherwise it might be to late. But if I do that, and if I am reasonably good at the game (so do not take many long rests) the story does not actually progress.
Imo, either it should be communicated, that the tadpole is bad, and should be removed eventually, but is no threat atm for reasons we have not yet found out, so we can take our time, or we must be able to progress the story by just going to camp without resting, or with short rests
