Even then, it looks like it gets set in KeymapModel$PL.run to "Netbeans"...

One could work around it with this:
try{
			ClassLoader allLoader = Lookup.getDefault().lookup(ClassLoader.class);
			Class<?> layerBridgeClass = Class.forName("org.netbeans.modules."
					+ "options.keymap.LayersBridge", true, allLoader);
			Object instance = Lookup.getDefault().lookup(layerBridgeClass);
			Method getCurProfile = layerBridgeClass.getMethod("getCurrentProfile");
			Object curProfile = getCurProfile.invoke(instance);
			if (curProfile == null){
				Method setCurProfile = layerBridgeClass.getMethod("setCurrentProfile",
						String.class);
				setCurProfile.invoke(instance, "Fluency");
			}
		}
		catch (InvocationTargetException ite){
			//it's a simple getter/seter, it shouldn't explode
			throw new AssertionError(ite);
		}
		catch (IllegalAccessException iae){
			//All items are public...
			throw new AssertionError(iae);
		}
		catch (ReflectiveOperationException e){
			//ClassNotFound and NoSuchMethod
			//It should exist...
			throw new AssertionError(e);
		}
		catch (IllegalArgumentException e){
			// The arguments should be right
			throw new AssertionError(e);
		}

It appears I forgot to remove the name of the product I am working on... Could an admin remove it please?

re-assigning to correct component. Please evaluate. thank you

A question: do you need a [default] profile with a different ID, or a profile with a different display name ?

If the latter, you can brand the NetBeans keymap folder in the XML layer (Keymaps/NetBeans) according to your product just as any other filename:

org.netbeans.modules.defaults.Bundle_product[_locale].properties:
Keymaps/NetBeans=FancyProduct
