The source references are optional. Since cmpfile() calls parse(),
setting options(keep.source=FALSE) should prevent it from adding source
references.

On the other hand, by calling compiler::disassemble() on the bytecode
values, you will still be able to see the language objects from the
file, so a somewhat lossy representation of the source code is still
present. These language objects are used at least for error handling
and sometimes for internal consistency checks [*].

What's your use case?
