    I have added a comment and collected some references on the renormalization freedom in the cosmological constant: here

    I have cross-linked this with related entries: renormalization, perturbative quantum gravity and stress-energy tensor

    I have expanded a little more. The most pronounced statement of the renormalization-freedom in the cosmological constant is in Hack 15, section 3.2.1

    added pointers regargind effective dark energy from higher curvature corrections, as in the Starobinsky model of cosmic inflation:

    This is the most remarkable development.

    I have added more prominent pointer to Witten’s Dark Fantasy and am expanding there in the “Phenomenology”-section.
