In my opinion, sometimes teachers "relearn" their first language as a result of teaching it. I would not want someone who has "relearned their language" to help me with my intermediate Spanish and Portuguese and my beginner level French. I want a clear view and understanding of the language I study as native speakers of the language speak it and write it in different situations, and that's what PROESL gives English language learners all the time - real language for real people in real situations.
In such examples as the one in discussion here, it could be better to speak of register and when the past perfect really becomes necessary to speak of a sequence of events. If the past perfect is not necessary in order to clarify a sequence of events, then just because it can be used to speak of a sequence of events does not mean that it has to be used as such. I've heard students use the past perfect in ways that simply sound stilted or out of place, and, sometimes, theyt simply use it when it's wrong in an attempt to simply use it for the sake of using it or because they think they should.
