FWIW, I see this as similar to the debate around being taught the 'lost' or 'forgotten' patterns - I think they were Ko-dang and/or U-nam - per the book titled the '16th volume' of the ITF encyclopedia. Personally - and not to take this off on a tangent - I don't believe they were ever 'lost'. There was a conscious decision to stop doing them and they are no longer part of the syllabus.
Now I have no issue with someone wanting to learn them and understand the history. However, the way that I look at it is that I have so much to learn that I don't have the time to spend any real amount of time perfecting it.
Another perspective - I hold Dan grades in both ITF-Style TaeKwon-Do and from the Kukkiwon. At one point I tried to do both styles simultaneously and I personally could not - the styles were too different and I started to incorporate part of the other into the other style.
So basically I do not think it is disrespectful to ask the question or to understand what came before - far from it - however I'd be more focused on understanding the why versus spending any real time on perfecting the performance of it.
