But, given Stansted's spare capacity, I don't think it will be even
requesting a second runway any time soon.

Apart from this (admittedly old) one?

That proposal was abandoned years ago by the previous owner. The current
owner shows no interest in investing in a new runway.

Sure, but there's a plan on the back burner. It takes decades for these
things to mature.
