Long bicycles need a more laid back steering axis to compensate for lack of weight on the front wheel, but this creates more wheel flop that is irritating on slow speed hill climbing. the only way to fix that is by shorting the trail.
Even cargo bikes could be have a more laid back steering axis, but I would compromise at 65 degrees.
Most people know nothing about trail, so they fall back on race bike steering geometry.
The reason factory bikes do not use this is simply the fact that they would have to make a special fork with lots of rake. Much too expensive.
Short bikes can use this method also. A chopper made with Zero trail would really handle well.
There needs to be some leverage, usually some tiller effect.
