But that's exactly the point - to make a compelling logical safety case (by lobby) to the regulatory authorities - CAA/EASA - that aircraft that currently operate on a permit, with suitable flight characteristics and equipment, are acceptably safe for the permit to cover flight in other than day VFR.
I don't understand your contention that e.g. Vans offering certified aircraft would be cheaper - that's certainly not the case in the US, where Experimental RVs have been flying in night and IMC for many years.
