A programmable FPGA SoM in the tiny microSD form factor

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.
