I think that those 'little' efforts could and should
be required precisely in the cases you have mentioned.
Most of the time there is no ambiguity and therefore
efforts should not be wasted.
In addition to the convenience of the auto wiring such
approach will help to avoid typos like
@InjectObject("service:tapestry.globals.Webrequest")
or
@InjectObject("service:tapestry.global.WebRequest")

PS: If this is a typical day on planet earth, humans will add fifteen million
tons of carbon to the atmosphere, destroy 115 square miles of tropical
rainforest, create seventy-two miles of desert, eliminate between forty to one
hundred species, erode seventy-one million tons of topsoil, add 2,700 tons of
CFCs to the stratosphere, and increase their population by 263,000
