if it helps you LGTM, but would you mind adding a TODO? it seem a bit strange to
write out duplicate info in an unnecessary file

added comment
    // TODO(jacobr): it is a bit strange we are writing the source map to a file
    // even when options.inlineSourceMap is true. To be consistent perhaps we
    // should also write a copy of the source file without a sourcemap even when
    // inlineSourceMap is true.
