I think place notation is more than a "method of description" - it does
get to the heart of the structure of a method. And structure is usually
a better guide to similarity between methods than blue line.
I also believe there are very many protocols for designing extensions to
methods. To my mind, if someone has a protocol that produces
decent-looking extensions, by all means use it. So if you had something
that works nicely extending bluelines for a subset of methods, I don't
have a problem.
It is of course possible to do extension badly. I agree with Roddy that,
if an extension introduces 3 blows in a place, and the parent method
didn't have that, you're probably doing something wrong, whether you are
looking at the place notation, the blue line, or some other description.
