It would be very helpful to manage material properties throughout different files, when they are linked, using its name as common ID. For example, let's suppose that we have a large residential building where each dwelling is a separate linked file, to handle multiple repeating units. And there are 20 different types of dwellings. And, at some point, we decide to adjust the color of a door type, but not creating a new color, just a little fine tunning.
The workload to open those 20 dwelling files to modify that material's RGB is worthless, and it's quite easy to miss some. Moreover, it would be so easy to do it in a simple step from the main host.
