Going from prototype to product is always hard, but if you can make your prototype part of your product, you end up saving a lot of time.
Shrinkify your projects with the Raspberry Pi Zero 2 W or undertake hardware projects you have postponed for want of a compute module that's small enough. It can fit in your wallet while still getting a quad-core upgrade compared to its last version.
The only disadvantages that I can see:
1. 512 MB RAM (Not a disadvantage for all projects)
2. Availability (CHIP SHORTAGE!!)
