At that point it’s so outside of what everyone uses MVP for, it’s likely best to just call it something else. Almost everyone who uses MVP uses it in context of lean, and it’s useful to do so.

Building a really refined product that outclasses on features or experience just isn’t the common usage of MVP. It requires dramatically different framing, strategy. Sloppy code and quick iteration don’t make sense.

In reality “viable” does all the work, it’s definition literally means whatever works best, so it’s almost just a poor term to use in the first place as it basically can stretch to mean anything.
