On the other hand, see https://news.ycombinator.com/item?id=33892009, https://www.raspberrypi.com/success-stories/korg-synthesizer... for example on how some companies use Raspberry Pi compute modules in their products.

Am assuming here that they're adopting strategies to minimize/work around the problems you mention.

The computer module instead of the standard Pi is the first step of those strategies. It doesn't use the SD card (in fact the data sheet gives details on how to configure the OS if you won't be shutting it down before removing power) and the device as a whole requires smaller electrical current that the standard device.
