Frankly as a ESP32 + arduino software stack user if they do it right no one will really notice. I've not had a single instance where the ISA was even visible.
AKA its 100% C++ code sitting on top of arduino wrapping various open source libraries. The result is that it can run on multiple microcontrollers after carefully tweaking the C based interrupt registration and a couple other small bits.
I've sorta wanted to play with the Xtensa cores, but haven't found a reason to.
