(linear tapering of extrusion rate for the 1st spiral vase layer)
Linear tapering could only be implemented for relative extruder distances.
For absolute extruder distances, all the G1 Exxx in all spiral vase layers
would have to be adjusted, which is much more complex and risky to do now
before release.
