I would say it's undermined by those who think the only technical solution is transponders. A far better approach would be ADS-B which
- Works even where there is no radar interrogating
- Provides a benefit to pilots of small powered planes / gliders - as opposed to just those with v. expensive / expansive electronics installations or those getting a radar service
- Is workable off a much smaller battery - so is more likely to be viable for aeroplanes with no generating facilities
but I suppose it's unrealistic to expect those who decided on Mode-S, way back when, to move with the times - it might look as if they made a mistake.
Just my opinion.
