In modern ansible, parameters default to string type. This causes
issues for polymorphic parameters like this module's value param. note
that this fix restores ansible-2.0 and previous behaviour but it is not
perfect. If a parameter is specified via key=value or given on the
commandline then it will be a string before it reaches the module code.
There's nothing we can do about that.
