I guess depending on where one places the filter (and to whom it is
applied), one could argue that this is a good thing.  It does make
troubleshooting a bit pesky however.

I once moved a router and forgot to reconfigure the IP address on its serial
interface.  Most "everything" worked fine and didn't discover my mistake
until I was troubleshooting my VOIP tunnel. |8^)
