Most projects have moved away from headers. They just get out of date and clutter things up. A license and docs in the repo root is just as legally binding.

It is what is it, dotnet/runtime follows this pattern as do other Microsoft repos and I personally like them :)

When a file is reused in another project, it is good to see where it comes from.

Origin of the file information is usually added at the time the file is pulled into another project. I know developers are usually too lazy to do this though.
