Stand Alone V L/R Plugin?

Hi, recently I asked a question from a user of Pure Raw who promotes it as many others do on YouTube as I have the problem when reimporting into L/R the process version gets changed from version 6 to version 1, understand that this is supposed to be getting looked at by DXO however in the answer I received they also stated that they don’t use Pure Raw as a L/R plugin but as a stand alone application then import into L/R, so my question here is “What if any is difference in doing it this way”? I am no expert so before anyone asks I am just looking for guidance from those who no a lot more about post processing than I do. Many Thanks in advance.
