It saves external components, buffers etc and makes it easier to pass
FCC and CE emissions testing, while removing it from the chip means two
chips and that costs money

A PC with all the LPC bus goodies is generally a three chip solution
anyway. The ISA bus vanished, some bits got integrated and an LPC bus
was added. By now the LPC bus and its contents have all vanished into
