i found all firmware after 16.1.27.2216.bin include 16.1.27.2216.bin have a same size. as i get it there no codes changes, only some correction of 16.1.27.2216.bin... in my system all of them works same cool i mean all of all from first day 25/11/2022. only bios versions 0904-1303 don't works with my memory... afaik firmware update it's only for make more simple way to communicate system with chipset + security. so i guess this can not be worse than older version, as bios can, because bios very complicated thing, what have to works good with many variable hardware. but chipset itself works directly with motherboard components that's standard certain things. so we can just update firmware without thinking it's can be worse than before. that we can not do with bios so far. i have situation that have to be very sensitive with any wrong settings, bios and firmware codes it's too high speed kits. actually i don't know other system that can take two kits 6400 memory at native xmp timings+voltages... but all firmware with 0703 and 0816 bios worked perfect. probably firmware can be clue to nvme which works out of cpu, and other pcie slots hardware. but i don't think this part of code changing, because this part, i think, write very carefully first days for works forever. because if not it can create much more trouble with hardware than bios can. from lost date to physical lost 3rd party components. but inside mobo where guys can test all mobo parts in supported chipsets, it can be write again and again:) but i join to the question, and would be cool to know how many stupid things i wrote above, because all of this my speculation:)
