I did some quick testing (commit 4716d5bb1e16 in pending branch) and it
does not seem to work for me:
oot@nuc1:~# echo assert > /sys/kernel/debug/ath11k/qca6390\ hw2.0/simulate_fw_crash
root@nuc1:~# iw wlan0 scan
command failed: Connection timed out (-110)
root@nuc1:~#
Kernel logs have:

Also there should be a clear ath11k_warn() message when firmware
recovery was successful, I could not find one from patches.
