Well then go ahead and call it silly.

There is/was a technology for this called Enterprise Objects
Framework, from which Core Data is descended.

It's a persistence framework for desktop applications. Why must these
things be relegated to boring server-side apps? Now any application
gets a persistence framework for pretty much free. If you want
client/server, you're more than welcome to implement it or use a
framework that does it for you, but Core Data is not that framework.
Besides, you should probably avoid serializing objects over a network
connection, it tends to be a very tricky endeavor, especially in
Objective-C.

You say "limitation," the rest of the world says "design principle."
