Yes? Clearly the market is there. And writing kernel extensions is a major PITA. One benefit of working in user space is that you can (usually) do so in the language of your choosing. Little Snitch 0.0.1alpha would have been a lot easier to prototype in Swift than in C.
I believe GP is saying that if the transition to kernel extensions had happened before Little Snitch was written, then LS could never be written after that point because they wouldn't have the required leverage to get Apple to expose the API they need.
What if we'll be missing out on other groundbreaking future apps that need kernel space information to function?
