Good software is the one that fulfills a need and pays the bills, period.

The Moon Lander software on the Apollo spacecraft probably had several defects, was unmaintainable, but it got the job done several times.

MS-DOS had several defects, was more maintainable than the above software sure, but it transformed MS.

Sure, it is better when the software is maintainable, more flexible, etc, and I don't advocate against it. What I do advocate against is overthinking all of this and not shipping.
