It's a compatibility issue, yes, but it's compatibility with a widespread
standard rather than just with your predecessors' mistakes.

I don't see the relevance of RS232.  Nothing except the UART chips ever
cares about the bit order on the wire; all the computers involved deal
with the data a byte/character at a time.  It's the same way on Ethernet:
the bytes are transmitted a bit at a time, but almost nobody knows or
cares which bit order is used.
