A better summary is: “people have different workflows because different people like to approach problems differently.”
That’s all it is.
I find LSPs largely get in my way. I don’t have them disabled because 1% of the time I do find them useful. But for the other 99% of the time they’re adding no value at all. So I could very easily write code without an LSP (and often do write code in vi with zero additional plugins installed).
What I do really value is code formatters. I like not having to write tidy code and then having code formatters clean it up when I hit save. That’s the kind of enhancement I value. (It also gives me piece of mind that a file has saved successfully when you see alignment pop into place).
