Continuity dependency

[Madis0]

The Continuity dev said that this mod

uses the SpriteCalculator class, which is strictly an implementation class that can change or be removed at any time without warning.

So, wouldn't it be wiser to fork said class into the mod itself (if possible by the license) or reimplement it? I don't mind the dependency myself, but that quote makes it seem like the approach is not very sustainable in the future.
