From the protoc --help:

  --include_source_info       When using --descriptor_set_out, do not strip
                              SourceCodeInfo from the FileDescriptorProto.
                              This results in vastly larger descriptors that
                              include information about the original
                              location of each decl in the source file as
                              well as surrounding comments.

We already support passing disable_comments to disable comment processing during the code generation.

However, when we compile FileDescriptorSet, we always pass --include_source_info. These might cause a problem, especially when the file is later included into the final binary using include_bytes! e.g. because of the following:

• The comments might contain sensitive private information (comments + file location) which we don't want to be visible in the binary (e.g. when someone disassemble it).
• It increases the size of the binary
