Would a fair solution to this be having the using class define whether to
inherit the implementations? Perhaps a new keyword akin to 'propagated', so
the code will read

Class Foo {
   Use propagated TraitName;
}

Only then will the implementations from that trait bubble through. If it
isn't declared then the implementations are not visible. This should keep
all backwards compatibility and keep code readable since now we can
immediately tell which traits being used do we want the implementations for
in the main class.
