Is that really the case? For example, while the following doesn't autovivify $h{A}{B}{C} it does autovivify $h{A}{B}.

use Data::Dumper;

my %h;

if ( exists( $h{A}{B}{C} ) ) {
    print "Hi mom!\n";
}

print Dumper \%h;

$VAR1 = {
          'A' => {
                   'B' => {}
                 }
        };
