I'll explain the motivation for 64 bit only DMD binaries:
1. It cuts the testing time in half. This is a significant deal for me,
as adding another hour to the test cycle slows things down a lot.
2. It speeds downloading the dmd package.
The only reason to have a 32 bit binary is if there are x86 Macs 10.5
or later that are incapable of running 64 bit code.
Well, you could ship the next DMD version 64-bit only and of you get
complains you bring back the 32-bit version as a universal binary.
But you'll definitely rule out users of Apple's early Intel computers.
I think the last Apple model with a 32-bit CPU was the "Mac Mini (Late
2006)", which was replaced mid 2007 with a Core 2 Duo model.
As for increasing the download speed, you could try one of these too:
* separate per-OS packages
* separate source package
* separate documentation package
* faster server
