Ha, since reminiscing, anybody remembers the good old SNA or god forbid SDLC
to mainframes and then rocking it over DLSW?
Oh or here's another one Token-Ring routing anybody? 

We came quite a long way from these to current EVPN and SR-TE...  

But still I can't shake the feeling that back in the days architects were
somewhat more ingenious coming up with these extraordinary designs to work
around resource or protocol limitations. 
Now it's just down to simple slap more cpu/ram/tcam at the problem and
you're done I feel. Nowadays boxes can easily take 5x the current 768 in
tcam and in control-plane -only sky is the limit, so for example there's no
need for any clever RR infrastructure designs anymore to hold all the routes
in your AS control-plane.
