Static analysis can very often determine which of the multiple functions
with the same name will be used at a particular call site. Yes, there
are exceptions (which will happen less frequently than with etags), like
when we're trying to jump to a virtual function with overloads in
several subclasses. But jumping to such function call from a file with
one of the definitions, and not being able to determine which of the
functions is going to be called, is going to be an even more rare
occurrence.
And even so, those backends can choose to sort the results starting with
the current file by default. No user option needed.

I'm saying etags' particular characteristics and varied usage patterns
justify the addition of an etags-specific variable.
I don't see much use for it for other backends, but if I'm proven wrong,
that proof would also provide some new information which would help
generalize the feature. This can happen at a later stage.
