I dont think so.
It can be part of the evolution though.
What I mean is, we start out as conventional heavy hikers, and find out how to lighten up.
Then once the big items are lighter, a lot of focus goes to smaller items, clothing/insulation. This is the "obsessive " part
Then finally, close attention is paid to the cal/oz of food so that the minimum food wt is carried.
Finally, you reach a point where you really cannot make enough difference to matter to you anymore without giving up comfort or protection.
Then you accept that you can still carry 1-2 lbs extra gear when you want it, and it wont matter either. So you quit obsessing about it.
I see the goal as being to reduce wt everywhere it doesnt matter, so that you can still comfortably carry more wt where it does when needed.
For 6+ day trips, I carry a heavier pack for the food load, would rather do that than save the 12oz pack wt difference .
For cold conditions I will bring heavier bag and heavier long johns, dont worry about the ~16 oz difference either.
For longer trips or hard ground conditions, a plush sleeping pad makes all the difference in the world. Would rather carry it even if 12 oz heavier than minimal pad.
Or expecting a lot of rain, that 2-3 lb tent offers better protection than the 13oz tarp setup. Would rather have it.
The obsessive part is over.
