Thanks, WiFive. From https://docs.espressif.com/projects/esp ... 32-rev-min:

ESP-IDF performs different strategy on different esp32 revision.

So, what does that mean exactly?

It is related to bugfixes that are required for certain silicon versions. If you know you will only ship v1 chips you can eliminate the workarounds for v0. If you know you will only ship v2 chips (future) you can eliminate v0 & v1 workarounds. However it isn't fully implemented yet afaict.
