The migrations from versions prior to 12 have not stopped yet, and I did
receive a complaint about it.  Because the change is so simple, I'm
inclined to patch it anyway, late though it is.

I decided to follow Tristan's advice to add the version number as a
parameter to the new function; this way, the knowledge of where was what
dropped is all in the callsite and none in the function.  It
looked a bit schizoid otherwise.
