I'd like to know when being explicit has ever been a problem.

It's a problem when return happens in array context -- you get a literal undef in the array. Contrived example:

use Data::Dump::Streamer;

sub filter_true { 
    if ( my $v = shift ) {
        return $v;
    }
    else {
        return undef;
    }
}

my @values = (1, 0, 0);

my @true_values = map { filter_true($_) } @values;

Dump \@true_values

Gives:

$ARRAY1 = [
            1,
            ( undef ) x 2
          ];
