We intentionally pulled the .filter. file information out of the .vcproj when we translated to the .vcxproj MSBuild format. One reason is exactly what you pointed out, that the filters are purely a logical view, and different team members may want different views. The other is that sometimes the build is set up to check the timestamp of the project file, and trigger a rebuild if it has changed - because that may mean there are different source files to build, or different settings, etc. I don't recall if we actually shipped with the build trigging that way, but the idea was that we did not want to trigger a rebuild simply because the filters changed, as they don't affect the build.
