I agree with your view.
IIRC, in the nineties, Heraklion had a couple of arrester systems for the Mirages based there.
We had to adjust RTOWs dependent on the system that was rigged because of appreciable restrictions to TODA. This often caused a lot of problems with available fuel for longish sectors.
We were only allowed to "trample", as a last resort, if we needed to cross, taxiing, after landing.
Good idea but too many problems.
