```Right, Filling is not a permissible option to ParametricPlot.

But suppose Wolfram wanted to make it an option. What, exactly, do you
propose it should do. For example, in what way would you expect a
Filling option to work with each of the following?

ParametricPlot[{Cos[t], Sin[t]}, {t, 0, 2 Pi}]
ParametricPlot[{s, t}, {s, -2, 2}, {t, 1, 3}]
ParametricPlot[{t, 2}, {x, -5, 5}]
ParametricPlot[{t Sin[t], t Cos[t]}, {t, 0, 6 Pi}]
