which boards are concerned? Which boards use ROMCC for romstage? Do they
output anything useful in romstage? If so, can't it be compensated by
ramstage?

Having to capture serial makes setup needed for board-status more
difficult. Certainely, one needs to have a recovery method for case of
brick but having a complete serial setup will heavily reduce
board-status input which already isn't huge.
