Re: Is it recommended/practical to use C++ instead of plain C ?
I use std::map, std::string, std::vector, find and iterators. The error messages are not nice and some things need just as much care for memory management as malloc/free because you can easily run out of PSRAM, it comes down to design and algorithm, and appropriate use and I would not criticise C++ ...

Re: RMT - simplest receive example working, but idle_threshold problem
Is that loop ever going to be blocked/yield or just burn up CPU cycles?

Re: FatFs does not work on encrypted partition
I got into the habit of only adding the encryption tags in the partition table only when flash encryption was enabled. It was not mentioned in docs, but it solved a few problems if I recall switching between flash encryption on or off.

Re: PSRAM cache - how/when to update toolchain?
Update: despite the smaller size, the toolchain and applications built with it do work.

Re: PSRAM cache - how/when to update toolchain?
Even if I rename the original toolchain, builds still work, but the new toolchain is 300MB smaller!!?? I guess I just don't understand these symbolic links and where they point to.
