Ah... that makes sense. It looks like IO0 needs to be pulled high to boot.
Still looks like you could redefine RX to a GPIO and still have 8 if you didn't need serial input. I vaguely remember running into this issue with some load cell AMPs.
A Shift Register or IO Expander seem like the more interesting and less frustrating route. I'd probably end up using an ESP01 and i2c IO Expander because I'm a masochist and love trying to squeeze as much as I can out of the ESP01.
