Since the mainboard BIOS is bought from Phoenix or Award or AMI or one of
their competitors and not written by the mainboard manufacturer, this
doesn't seem to be a likely motivation.

One could argue that the 32-bit addressing limit in IDE was there to "force
the customer to buy new hardware". In fact that limit is some 5,000 times
larger than the largest drives on the market when IDE first shipped, so it
seems more likely that it never occurred to anybody that PCs would ever
have drives that big.
