You could use the same argument for everything.

Small "unless" and you are forced to make all your APIs generic because there might be many clients. Small "unless" and you'll ignore all power features of your database and dumb-down your approach to data because user might want to switch a database. Small "unless" and you will make your app ultrascalable even when you have no proof there'll ever be more than 100 users.

This is a disease that makes development slower and more expensive even when 95% of time, the customer needed something fast and cheap. No, most devs aren't building another GMail, most devs are building something that could have been modelled in 2 weeks in Visual FoxPro 25 years ago.
