It is more than likely that since Rhino has dedicated commands that are not editable in function that the development of the "Meshoutline" has been scripted to cover many conditions over time. So if you run that command on a surface that has holes vs doesn't have holes lets say, it probably performs a different operation behind the scenes. (you have to remember people spent many years updating those commands to cover various conditions) However, Grasshopper is "deconstructed" into core operations. So you would need to implement a slightly different operation for each kind of surface condition. You could then run some tests in your definition with components like "is planar" "is closed" etc. and based on the boolean true/false results run the appropriate part of the gh definition.
