Ho hum, so you havent yet answered my question, if long stem fibre is soo important for horses then how do you propose I get it into a pony with no teeth?
And why is my 30 yearold no teeth pony who has lived on a diet of alfabeet, grass cubesand premixed feeds, perfectly healthy, perfectly happy and not had a single case of colic since we started him on this diet when he used to have regular bouts of colic despite bing on a 90% grass and haylege diet.
I also think that before you link to articles you need to read them correctly.

Actualy says alfalfa is better nutritionaly and only mentions long stem fibe is in relation to the horses insinctual need to forage and chew. This is more a mental requirement and not a physical one.
I'm not going to bother signing up to a rediculas amount of sites in order to read the articles you want me to. However one thing I will say is that I think you are taking things to extremes and very obviously can't accept any other view then yours.
I read chemical engineering at university, so don't try to baffle me with science it won't work!
