I mean it's not hard to understand where the author is coming from. It seems like these days even a hobby project has to meet some kind of 'is there a market for it' threshold of justifying its existence.

So your parent may've taken the 'is it useful' comments to mean 'if not, why even exist' but I got the sense they're more from people who are considering an install, even if just in a VM.
