Not the same runway admittably but I once had a go around on rwy 27 LBG and it's equally ambiguoius G/A procedure. This was also pre having everything in the FMS. As soon as it was announced "going around" the return call was to contact CDG app who radar vectored us around the houses back to a LBG ILS. So I kinda think the go around published proceedure is just filling the legal requirement to publish one. In reality, it is much easier.
