Would it be enough to be worthwhile at all though, even ignoring the cost of the control circuitry? (and what's the laptop going to do when it sees 5 power sources? How does it know not to charge one depleted battery module from another?)

Some thinkpads already come with two batteries. The program tlp knows how to handle charging and discharging two batteries very well. It just does them one at at time in a given order of priority.
Sure, but these modules are about half the size of a phone, even all four would be considerably less capacity than a full-size spare.

Yep I have a thinkpad T580 with two batteries and it works flawlessly on Fedora and has for the 3 or 4 years I've owned it.
yeah, definitely concerns there. I honestly don't know. I think it'd be interesting if they considered a single "long bay" as an option on future models that could accommodate a few battery cells or something else like an extra m.2 slot.
(I kind of suspect you might be limited to one though, assuming the power delivery controller can only really handle one external source of power)
