Oh, i think i see - create the transform and attach the hit region to it, once. Then add-child this transform to child_transforms_ on each frame submit. Right?

Yes that is correct. I initially thought that a transform had to be added as a child before setting its hit region. Turns out I was wrong. Fixed !

Can we call it input_interceptor_transform_ instead? Node is a gfx specific resource.

Gfx is adding the child here, so lets just follow that? We should also add it to child_transforms_.
