Get the true vertex count (Arcade)

[Bud]

Using an Arcade expression:
I can get a count of a polyline's vertices by looping through the paths property:

var line_geo =  Dictionary(Text(Geometry($feature)));
var paths = line_geo['paths'];
var vertex_count = 0

for (var path_idx in paths){
    for (var vert_idx in paths[path_idx])
        {
        vertex_count++
        }
    }
return vertex_count

 

That code works, but the vertex count is a densified vertex count, which isn't what I want...I was expecting the vertex count to be 3 vertices, not 35 vertices.

Could ESRI give us a way to get the true vertex count? For example, a pointCount() geometry function.
