I get the impression that they don't actively manufacture Pi Zero W anymore and it's all old stock. Rapid for example say they have an availability of 761 (at time of writing) [1], but are those all within Rapid's control, or what is reported at Raspberry Pi's remaining stock? If you sell 1k printer units, can you put a Pi Zero W in all of them?
Compute modules are probably a bit more reliable and there is some capability with other modules, specifically the DDR2 form factor ones [2] (which is my favorite form factor). For example, ClockWork sold their own compatible compute modules [3].
I agree with the rest but Pi Zero W is a specific machine with 512 MB RAM:
