Small, but significant point: you can easily avoid the new behavior. IIRC, if you had a pre-1.22 project, and didn't change anything, it still compiles as before. So if you relied on that behavior (which would be very weird, but who knows), backwards compatibility is still there for you.
It defaults to the new behavior. If you want the old behavior, you had to set a flag on the compiler. But this applies to all code, so any libraries you include would also get whatever behavior you set on the flag.
