Yes; we all understand DxO is not like Lightroom. It has different tools and different logic.
At the moment we have in Local adjustments: Control point, Brush,Graduated filter, Eraser and Auto select.
None of those tools are direct replacement for Radial filter. We can improvise but…
So; how much harm can we do to DxO Photolab if we add Radial filter to Local adjustments?
I personally find Radial filter very usefull. It’s basically Graduated filter with different shape.
