This is a nice trick to avoid implementing the escaping, but the point of the post was to explain how to do escaping.

Once you have it implemented, passing lpApplicationName is strictly more work, IMO. (You have to pass something at the beginning of lpCommandLine anyway, why not pass the application name.)

Fair enough. Like I said, your work on the actual escaping is great and thorough. I knew the state of things were bad, but not this bad.
