 No, we can not break the ABI on release branches (module loading code
 does not check the patch level field on != .99 branches).
 
 We would need a proper fix or hack especially for the branch that avoids this.
 
 Maybe duplicate the function that got an extra argument with a new name
 and use that everywhere the new arg is important?
 So all new compiled modules would also use the new function, but old
 modules still would work using the old version.
