signals versus vfuncs

[muppet <scott asofyet org>]

forgive me i'm completely off my rocker here, but i seem to recall 
discussion on this list not too long ago to the effect that ... whereas 
in the past convention dictated that all overridable methods should 
have an associated signal, this is no longer the convention.

is this correct?  if so, what's the rationale?  i understand that 
overriding class closures and calling g_signal_chain_from_overridden is 
odd and clunky and all that, but having the marshalling metadata around 
for virtual methods is really important for language bindings!
