That was back when it was safe to assume that those one or more
destination wanted to receive anything that showed up on port 25.   Or
that you could reasonably accept the unwanted data and subsequently
send it back to wherever the From: line said it came from.   Which was
basically never but people used to do it before they knew better.

Not a good analogy.  Cars have a fairly useful user interface for the
decisions drivers need to make.  MTA's need to have helper programs
hooked into various places that are much less standardized to make
some decisions for you.
