It may be possible that occasionally liquid refrigerant does reach the compressor and that could be a contributing factor to why the original compressors didn't last very long. But, I don't know.
It may be a worthwhile safety device in case the expansion valve malfunctions or there is a low-load condition. I really don't want to add one, though. But, if it's one of those things where they started adding them in later years because engineers found that it prevented early compressor failure, then I'd probably want to add it (though it would be really awkward and inconvenient).
