My understanding is that the SDK is what allows an application to use 
and link against system features, i.e. it contains header files, etc.

It does not contain the libraries themselves. Installing the 
MacOS10.6sdk on 10.5 would allow to build an app targeted at Mac OS X 
10.6, on a Mac OS X 10.5 machine. But that won't bring 10.6 features to 
the 10.5 machine. Years ago when I used to write programs for Classic 
Mac OS, the common practise was to do "weak linking" and check at 
runtime if a particular symbol was available. I don't know if this is 
still a thing. This is the only case that I can think of where just 
installing the 10.6 SDK might be useful.

So what needs figuring out is what is Grand Central Dispatch used for, 
and can it be disabled ? Then you would need to build for 10.5 with the 
Grand Central Dispatch features disabled. Since Grand Central Dispatch 
is Apple tech, and vim works on a variety of systems, it would be highly 
surprising that this is an actual requirement.
