Yes trying to abandon U-Boot and the MPU concept are neither of them
random ideas :-)

It's quite a little area of physical space, and I pulled the battery
many times and it never made a crash, the PMU is pretty decent at
handling that.

Whether it makes a "feature" if the phone suspended on battery removal,
survived for 20 seconds on the goldcap so you can swap the battery and
resume, I dunno.  Inrush current from the battery would need managing
with a series resistor is all.
