I have a project that we actually plan to use in production in the 
company for which I work. They still require 10.5 support for their 
products so removing that support would make for a very bad situation here.

But it should be possible to get a 10.5 retail DVD and install it inside 
a VM.. I actually planned to do exactly this to support 10.5 nightbuilds 
for my own D stuff.

If support should be dropped anyway, are the issues only build-related 
so that e.g. gdc would still continue work on 10.5 without further work?
