(SymbolGraphGen) emit project-relative paths instead of absolute paths in documentation archives?

SymbolGraphGen currently emits absolute paths in symbolgraph files:

"location": {
        "uri": "file:///home/ubuntu/package-name/Sources/Module/main.swift",
        "position": {
          "line": 1,
          "character": 9
        }
      }

is there a way to configure it to emit paths relative to the package root instead?

"location": {
        "uri": "Sources/Module/main.swift",
        "position": {
          "line": 1,
          "character": 9
        }
      }

There doesn't seem to be a way to do this right now, but i can see the appeal for something like reproducible symbol graphs. (This would combine well with the "nondeterministic ordering" bug for allowing symbol graphs to be checked into Git repositories, for example.) Can you file an issue on SymbolGraphGen for this?

For what it's worth, the clang symbol graph generator suffers from the same problem.
