IDK if failure to cerate a MFnDependencyNode should be treated as failure. A node not being a MFnDependencyNode is not an error, it just that the node does not support the API.

It should just skip the type check.

The flag is passed explicitly here, so changing from "Meshes" to "mesh" seem feasible without modifying UI shown to teh user.

I don't know if that will confuse the user.. Like they see "Meshes" in the UI but when use it in command it changes to "mesh". They won't know it unless they read extra documents to get that information...
