It used to be the standard on motherboards but it was removed and replaced with marketing stuff like RGB.I have the ASUS X870E motherboard and i have to admit the LED debug screen is a useful touch. Should be standard on all high end motherboards.
I had an MSI Z77 Mpower which was great and had the debug code LED. I even had an Asrock ITX Z77 motherboard with one on it.
Bring back LED code readouts and bring back the DFi LanParty series with its UV reactive PCI-e lanes is all I can say.
