Radial Dimension Bug / Missing feature

Like Linear Dimensions, Radial dimensions can be set to “align to dimension” rather than “align to screen”. However, Radial dimensions with that setting do NOT align to the dimension.
That setting instead aligns to text to the X axis, not to the dimension.
The dimension line is represented by a (partial, variable length) arc radius.
It would be nice to have the text aligned to this line both horizontally and vertically (relative to the line) in the same way tha linear text does.

Another alignment option commonly found in the wild is arc dimension text which follows the curve of the arc, as in land surveys.
