I updated the postmarketOS wiki to something similar to what you have because on some old rk3288 devices the futility flash commands they had failed.

One thing you might also add is that /usr/share/vboot/bin/set_gbb_flags.sh without any arguments will print out the list of all the allowed flags, and /usr/share/vboot/bin/get_gbb_flags.sh -d -e will show you the current flags "sum" and DESCRIBE the ones that are active. You can also use this against a backup ROM so if you used flashrom -p linux_mtd -r somebackup.bin to make a backup, you can supply the path to that and run get_gbb_flags.sh to view the flags that were set when the backup was created.
