One of the problems in having a single gitignore to ignore all the possible things that there's no strict superset without overlaps. Visual Studio uses files called .user that contain user-specific metadata that should never be committed to source control and other systems might use .user for components that should be committed to source control. Breaking it down by language ecosystem seems an adequate compromise as few repos use multiple languages and when they do there's often a folder hierarchy to respect with nested gitignores.
