That statement can be made about any developable surface calculated between two curves by any or almost any computational method.
DevLoft does have a limitation which the user can work around. For many pairs of edge curves the user needs to extend and trim the edge curves so that the corresponding ends of the edge curves are tangent to a plane, ie “no twist”. I’ll try to find time for a more detailed post on how to do that. Other than that limitation DevLoft works very well in my experience…
