I kinda thought modern microcontrollers have this sort of thing built
in? Oh, looks like the Pico (no W) draws 2 mA in "deep sleep" and this
timer draws 35 nA.

That does sound surprisingly bad for the Pico. Seems that the RP2040 is
0.18mA in 'dormant' (ie deep sleep) and 0.38mA in 'sleep', which is a bit
better. So must be something else on the Pico that's not so good in sleep
mode.
I think (ultra) low power was not a primary design goal for the Pico.
