An issue is that the previous releases still exist (retail Mac OS X
Leopard boxes are still 10.5?) and that someone may need to support

Let me re-emphasize one point: I'm referring to new development.
Given the APIs and technologies in Leopard, its maturity within the
marketplace, the sales rate of Macs, the typical multi-month app
development cycle, and the extremely high upgrade rate for previous
owners, targeting new development to Leopard only makes a lot of sense.
I have a stupid question too. Considering that I sometimes see
warnings in Console.app related to Garbage Collection, does this
mean that:
- the issue is in the application (Xcode sometimes display warnings
for instance) and not in the GC?
or
- that GC is more complex than retain/release in some cases?
The warning you are referring to is likely this one?

Xcode(21294,0xb0103000) malloc: free_garbage: garbage ptr = 0x39f3fb0,
has non-zero refcount = 1
It is a known bug in the Apple frameworks that is unfortunate, but
harmless at runtime.
It is no indication of GC being more complex. It is simply a bug in
Mac OS X, of which there are several :), and some of the bugs cause
noise in Console, GC or otherwise.
