Comment (by ericlewis):

 Yeah, after thinking about it, I agree. No validation at all would be
 better to create the proper PHP errors, while silent invalidation could
 lead to even more hard to track issues.

 It looks like the array cast on $wp_filter[$tag] came from #4394, marked
 as code clean-up. I'd imagine that's good for taking out as well.
