We used to do kernel module development directly on Pi3/4s at this one client of mine, and I would OOPS the kernel from time-to-time (couple of times a day on average in the beginning stages) and never had a loss that ext4 couldn't recover from (and as the Pis lacked a "reset" button, resets were done via power-cycling). We used standard PNY/Samsung Micro-SDs, too (i.e., not industrial-grade varieties), but we did pick the faster-IO variants when possible.
