FWIW I 100% concede that there are uses for LTS systems. For things where active development means releasing a new product that customers replace their old one with, go for it. For systems not under active development like a nuclear plant control system, go for it. I don’t think those audiences make up a significant mass of HN readership, so my comments aren’t targeted at them. For your SaaS company with 20 services and growing? You will have less pain from constantly upgrading than you will from adopting LTS releases.
