I disagree. If the function of the function changes that much, that
you need a different docstring just because you pass in a different
number of arguments then there is something terribly smelly.
What are the major use cases of variable arity?
For me this is default values:
(get a-map a-thing the-default) vs. (get a-map a-thing)
(sort comparator a-collection) vs. (sort a-collection)
This does not deserve a different docstring. This can be well
handled in one.

I don't think, that this change is worth the trouble.

You can always use:
(defmulti #^{:arglists '([a b] [a b c]) :doc "bla"} foo identity)
Docstrings for individual defmethods are not possible. While
I also wanted to use it before. Rich convinced me, that it is
a smell when I have to.
