That's one reason. But what I was thinking of is when some things are actually just technically infeasible, and devs lose their minds and scramble around trying to figure out how to deal with that.
Haha. One of them is follow counts. Reading discussions about them is pretty popcorn worthy on the NIPs repo. How do you count how many people add your public key to a list when they don't put that list in a place you generally look at? That's a pretty good one. Nearly impossible, but people like to know. It's like voodoo. I can stab things in a doll that looks like you across town, but how the heck would you know? That's impossible without magic involved, but at least a follow list exists somewhere that's publicly accessible.
