> It's legacy in the "we would never invent this as the solution to the problem domain that's today asked of it."

I don't think that definition of legacy is useful because so many things which hardly anyone calls "legacy" fit the definition - for example: Javascript as the web standard, cars in cities and bipartisan democracy.

I think many of us would say that that none of these is an ideal solution for the problem being solved, but it's what we are stuck with and I cannot think anyone could call it "legacy systems" until a viable successor is widespread.
