Beacons Redstone compatible

It whould be so cool if Observers in Java could detect if a beacon is blocked or not and also that comparators could detect for example how many glass blocks are above the beacon and could give a redstone output with the strenght (1-15) depending on the amount ob transparent blocks „blocking“ the beacons beam. Imagine the possibilities you could easily transport redstone signals vertical in late game and detect things like flying machines blocking the beam. Maybe its a bit useless but why not? It would be just a small change that could make vertical data transmission literally go with the speed of light
