Hmmm...I never played 2e, but in 1e, in the 80s, plenty of us had favorite characters that we kinda expected to continue living. Finding a temple to pay a bunch of gold to for a res was a thing in many 1e games at the time.
The big difference to me (not saying same is true for all), but in the 80s we would bring our characters from one DMs game to another. And most DMs were would just piece run a module or an adventure they prepared without any long story arcs. The whole adventure path wasn't a thing in the groups I played with.
