The old esp32 -factory stuff along with the lws support doesn't have a
future in its old form.  It has users but the ratio of effort to
contribution is really especially bad.  I haven't updated it for more
than a year since esp-idf changes broke the original stuff.

Freertos plat is alive and well and getting a lot of new use, ESP-32 is
supported both there and by modern lws_drivers pieces, including in CI
on real hardware, any further effort will be invested in that direction
instead of more vendor api-specific code (outside of wrapper
implementation).

lws_drivers wraps any SDK apis in generic lws apis such that your code
just uses those, enabling it to become SDK / SoC / vendor independent.
Its first implementation is on esp-idf, the low and mid-level features
that were in the old -factory are already available using that and
new technologies like lws_struct and Secure Streams.
