Bug with ReplaceEdge

When I use ReplaceEdge with Mode=SelectCurve and select a curve with a G0 transition, the resulting surface edge is a single segment instead of 2 segments.

Can you explain if this leads to practical problems?

I’ll let you know when I run into a practical problem with this.

But, fwiw, I don’t think there are any other ways to create a single surface edge with a G0 anywhere in Rhino, which is what lead me to assume it was a bug.
