I know the ESP32-S31 is new, Would love to see a " M5Stamp ESP32-S31 Module ", much like your M5Stamp ESP32P4 Module.
Unlike your M5Stamp ESP32P4 Module which has a operating range or 0 ~ 40°C, maybe you can make 2 versions. One for general people who could use the 0 ~ 40°C, but for more serious people that would use it as a simple plugin module for new designs for industrial use, extend that range.
