We are going to release a licensed update to the Name by Layer TML that provides the ability to Color the objects as well as set the Linestyle, Line Scale and Line Weight parameters to the By Layer values of the layer if they are not already assigned specifically to the object. This allows you to then Import the CAD file, run this command on all of the linework, so each line now has the specific properties that it came in with, so that if you then relayer the data using Standardize or Map Layers or using Relayer commands etc that the linework will carry its original source information with it, so if you mis classify something, you can review its original information without having to go back to the original CAD file.
It does depend on what you are doing as to whether or not you want to use all these options, but I can for sure see high value in this for Data Prep workflows, at least while you are getting the model built.
I could then see people selecting all the information and clearing the names and then using the command one more time to take on the names of the final layers before taking the data to the field.
Thanks for the input Wayne - I hope to have a Test Version for you to look at later today.
