Seriously, was it one of those things where a vendor started doing it first (pre-standard) as sr, and then ietf started standardizing it as spring ? …or was it always being standardized pre-vendor implementation and there was a disagreement within ietf or elsewhere ?  or… was there a conscious decision amongst the inventors to actually call it both sr and spring ?  or is their actually something different about each one and I’m wrong in thinking they are 2 names for the same technology.

If you don't like the names, I have others.

SPRING is the IETF working group name - Source Packet Routing in Networking
Segment Routing is under SPRING
