I tried recompiling the brewpi firmware for ESP32 a few months ago. It didn't work. I'm pretty sure it's just that the ESP32 port of the various Arduino libraries still isn't that mature, and over time the issues may just kind of resolve themselves.
That said, there's really no advantage to the ESP32 for this use case - aside from the additional pins. It's more expensive than the ESP8266, MUCH harder to locate, and the additional power really isn't necessary in most cases.
