The proper way to do it is by either building on 10.6 against the 10.6
SDK with a deployment target of 10.4, or building on 10.4 against the
10.4 SDK.  Otherwise you depend on the API never, ever changing.
That's an unreasonable expectation.

You should, however, be able to depend on behavior not changing when
you've built an app against a certain SDK.  Any case where that isn't
true is a bug, and you should file a Radar.  That includes when
methods are deprecated in the 10.5 SDK but you're building on 10.4 --
a situation which has bitten us quite frequently.
