Probably because the charging circuitry would make the electronics inside bigger, and a rechargeable cell has a massively reduced capacity compared to a primary cell. The electronics package is tiny, and the battery itself is by far the biggest component. I think it makes sense to keep it semi-single-use with those factors in mind.
In fact, I’ve considered 3d printing a new shell for it to make it even tinier and definitely water proof.
Wow yeah that sounds really stupid, I wonder why they didn’t just make it rechargeable via QI
