Whoa, you said that, not I. When I've implied that in the past, they
offered me a tinfoil hat and trotted out Hanlon's Razor
[https://en.wikipedia.org/wiki/Hanlon%27s_razor] as their justification.

When I transitioned from a hobbyist programmer to a professional one, I
learned pretty fast you need to please the custy, and unless you're
sure you won't be the one fixing it six months from now, you need to
make it simple and robust for future changes/fixes. And as a hired-gun
programmer-analyst who wore his salesman hat one day, his systems
analyst hat the next three, and his programmer hat the next three after
that, and his debt collector hat after that, I learned that us one man
bands don't have time for scope creep.
