I fail to see how this proposed behavior solves anything. Most software out there was written to assume that if you get back an address DNS resolution worked, if there was a problem you get back something like NXDOMAIN. Lots of apps are not going to report any problems if they get back 127.0.53.53, there are going to sit and wait for the connection to time out or depending on how the system is configured report connection refused. Leaving the user with no way to know the name was wrong.
It should be connection refused for most client systems. Because 127.0.53.53 is smack dab in 127/8 space - aka localhost space where all connections inside of 127/8 are supposed to resolve to itself, despite the actual IP used. For the few that have actual services in use (FTP, HTTP, etc), it's going to lead to a confusing mess.
