> People do understand it. Often, deeply understand it because they wrote it, and have lived and supported it for years. They know the reason behind the tech debt, all the odd tech constraints that drove it to where it is, they can keep the thing running without breaking a sweat. It is second-nature to them.

I don't think it counts as legacy code if the original devs are still around to work on it

Legacy is not just "old" it is something that was left behind by someone else
