The argument is that the OP on this thread is asking for advice before commencing. In the other thread you are referring to the vast majority of the work had been completed, apparently to a satisfactory standard. Clearly stripping it out wouldn't have achieved too much. If they had asked before starting they would have received the same advice offered in this thread.
I'm sure you've joined some pipes in your time that in an ideal world you'd have done differently but you don't always have a choice.
