Though it is cool to see a minute FPGA dev board, I don't see the value proposition here. At $45, it is too expensive to use in a product. What is the killer app for this board?

One can get a significantly more powerful Tang Nano 20K [1] kit on Amazon right now for $31 [2].

I think it's to add logic to an existing COTS device.

Say you have a widget that both writes log files to an SD and reads a command script from that SD. With this FPGA card, you could implement logic that changes the command script based on the content of the logs.

No you can't, there's no meaningful storage on this pcb. Besides, you could do the same with a dirt-cheap rp2040 or similar cpu. What's the FPGA added value?
