Sure, if you're going to dump your project in 6 months like a hot potato. Any coder that takes pride in their work knows that constantly piling on more tech debt to push thing out faster only slows down your project in the end. The only exception I can think to this is very early start ups, where if you don't get a product out in 6 months, then the project won't have a future to think about.
I think most companies do do this, on a rolling basis with different parts of the product.
Except by “dump every six months” it’s more like “after six months don’t add much to that anymore, unless we can dedicate a good three weeks to hacking it into place. And then dump the whole component in three years”.
Since your customer base and business requirements are likely to turn completely over in 3 years this makes some (perverse) sense for a startup.
