Re: Certification status (FCC, IC, et al) of ESP32-WROVER/WROOM with 8MB, 16MB flash?

Unofficially yes because changing the flash chip size should not degrade the rf characteristics and as such no new filing is required but you may want some official statement for the lawyers. As long as they have the markings on the shield it would be good enough for me.

Ok but say a IPEX cable falls off during shipping. Is there a way for the phy to detect this and notify the application?

Re: ESP32-PICO-D4 integrated 4MB SPI flash connections

Yes application is executing from flash so it is best to use one large flash chip, in which case you don't save much space with pico 7x7 vs 5x5 and pico costs more.

It is possible to do very compact layout https://fccid.io/XPYNINAW15/Internal-Ph ... os-3854229
