This looks plausible to me -- I need to get some ws2812s attached to an esp32 to test.....
The module name might have become a little bit misleading. It is not ws2812 specific, but works with a lot of other RGB LEDs. I did my tests with a single SK6812 on the ESP32-C3 devkit. Another unknown LED strip from some home improvement store is on the way.
But there are other led strips which will not work, so that would be as misleading.
@docbacardi @pjsg any chance of seeing what needs tweaking to make this compatible with the current IDF5 branch? I'm out of my depth with the RMT stuff.
I will try and port this. Also a good chance to move to the new RMT driver.
Please find the patch here: #3629
The migration to the new RMT code in IDF5 would affect more modules. One step after another...
Fixes #3508.

.This patch replaces the custom ISR in ws2812.write with a translator callback. Furthermore it introduces 2 small improvements: 1) If the hardware supports it, all channels in the write request are placed in a group. This moves the start of all RMT sequences much closer together. On my hardware I observed >=50ns . 2) New optional parameters can set the duration of the reset signal and the duration for the high and low phase of the 0 and 1 symbols. This allows to adapt the timings to many other RGB LEDs.
