Because as far as I know, Inkscape can only handle cubic Bézier curves
(when I open something with quadratic Béziers, they get degree elevated to
cubic Béziers).

The tool says "Bézier curve", so the object should either be linear (a
straight line), a quadratic one, or a cubic one. If there is just one
handle, that suggests that it is a quadratic Bézier curve. But that isn't
the case -- when I look to the saved .SVG file, it says that it's a cubic
Bézier -- which should have two handles, since you need 4 points to draw a
cubic Bézier curve.
