[ih] Source routing

[Dave Crocker]

My recollection is that mechanisms for source routing were common in the 
early days, but lost favor.

UUCP networking (!) was a version.  SMTP originally supported it.  I 
don't think Arpanet packets did, though I have a vague sense there was 
some selectivity allowed.  And I don't think IP did.

I'm curious about a rough summary of when and how it was used and when 
and why it lost favor.
