Move deprecated function back to the only class that calls it

Move deprecated function back to the only class that calls it

This function is only called from the importer (in core) - copy back there & noisily
deprecate (one known extension usage).

Note that I removed 2 parts of it in the copy back that are unreachable
as only specific params are passed in we know they don't include
case & always include skipRecent
