I think this boils down to a cost problem more than an engineering or cultural one. If you look at the original Itanium machines of the early 2000s, they had BMCs like the Sun ones, and they ran EFI as the base firmware, often with no graphical head. Pure serial!

There's no reason you couldn't build a solid, headless PC-compatible architecture based around EFI. It would just... cost money. Even in the retrocomputing stuff you see the same thing happen. Older VAXes had very rich boot PROMs, but by the time you get to models like the 4000 "Very Low Cost", most functionality was stripped out of the PROM to save space and cost.
