Mainsheet traveller vs bridle

as others have said the traveller is an old idea - and current thinking has all but eliminated in the mainsheet in controlling the leech of the mainsail  -  in the 'old days' a kicking strap was a 2 or 3 :1 tackle  with a v cleat  vs the 12:1 , 16 :1 or more mechanical advantage in cascade kickers , with cam cleats adjustable whille fully hiked ...

From a tiller/rudder wrangling point of view doing away with the traveller would make life much easier. Allowing a fixed rather than removable tiller, or if you already have a fixed tiller allowing easier fitment/removal.
