As usual, I have a feeling the answer is 'no', but doesn't this take
care of it (maybe with improved ignorance of callback methods)?

module Foo
  def self.included(c)
    singleton_methods.reject { |e| e == 'included' }.each do |m|
      mod = self
      c.class_eval do
        (class << self; self; end).class_eval do
          define_method(m, &(mod.method(m)))
        end
      end
    end
    nil
  end

  def self.foo
    :foo
  end

  def self.bar(baz)
    baz
  end

  def joe
    :joe
  end
end

class Baz
  include Foo
end

p Baz.foo
# => :foo
p Baz.bar(:bar)
# => :bar
p Baz.new.joe
# => :joe
