Spot on. I was so excited to see the form factor, and then my excitement was deflated as soon as I noticed the component details.
Note to any hardware hackers out there: I would buy the crap out of a unit in this form factor with an ESP32, LiPo charging, and proper deep-sleep oriented circuit design (I have seen too many circuits with cheap voltage regulators leaking many tens of μA).
