System Information
Operating system: Windows 7 64bits
Graphics card: GTX980 Ti

Blender Version
Broken: 2.83 ad317a5ffdcf
Worked: (optional) 2.82

Short description of error
Extruding a two vertex spline curve no longer works

Exact steps for others to reproduce the error

Create any default bezier curve object with Shift+A > Bezier
Enter Edit Mode and select both vertex of a two vertex spline

Press `E` to extrude the curve

Demo file CurveExtrude_Bug.blend

It should create two new segments on the spline ends, but instead, moves it.

This is almost certainly related to the curve extrude operator improvements to allow extruding mid-segments.
Selecting only the end handles also only moves them, whereas before it also extruded. For splines with more than two curves it works as expected and so does with a single vertex selected.

Ideally the old behavior would be brought back, but there may be a design decision to solve here.
Should it extrude the two end vertex like before, and create two new end segments; or should it extrude the segment between them leaving the ends in place and creating a new mid segment instead?
