UL advocates might not see using a bivy and a trap, or using a single walled tent, or going rackless as extreme, but most of the touring community will. And this is where I fear that our "fully loaded" fellow tourists will see this approach as Stupid Light and so fail to adopt some of the ideas to lighten their own loads.
That is probably true for some at least, but... I will say that I have gotten a lot of nice "thank you" emails from folks who pack pretty heavy and will probably never break into even the light range, but who none the less used some of my ultralight hints from my article to lighten their load. So some of the heavier packers will still use info that we share even if they find much of it way beyond anything they would consider. I figure that even though they may consider going with a sub 10 pound base to be way more extreme that they have any desire to do they at least are armed with the knowledge that it is possible and therefore may make more moderate weight reduction efforts themselves.
BTW: I think that those we actually meet on tour are more likely to be open to adopting some of those ideas if they camp side by side with us for a ways rather than just reading about them on a forum. I have had comments like "I had no idea that could actually work so well" from folks who I camped with when they saw that I really wasn't lacking for anything.
