Message:

Coding Standards: Remove unnecessary unset() calls in WP_Importer methods.

Variables created within the scope of a function are discarded automatically when PHP leaves the scope of the function, i.e. on return, so doing a call to unset() straight before a return statement is redundant.

Props jrf, ravipatel, rachelbaker, mukesh27.
Fixes #52996.
