I believe there are a number of breaking changes in ESP-IDF v5.0, but as v4.4 is already in the maintenance period, and will be unsupported in Jul 2024, at some point we will have to move off it.

Also, some of the newer chips (C2 & C6) are only supported in v5.0

Wondering if the changes are massive, and whether it is worth starting the work now (maybe for the 1.20 release) rather than waiting?
