Eric is our technical lead for file system and works in the broader file system 

What Red Hat supports is determined by lots of things - some of them technical, 
some of them practical.

Practically, we try to focus our testing and resources on the most common 
platforms for enterprise users. 32 bit is not that common and certainly not a 
reasonable choice for large file systems. Most new enterprise class servers are 
64 bit these days and have been for years.

I can say that as Eric's manager if that helps :)

Just to be clear, this is a *Fedora* list, not a Red Hat or RHEL list, so what 
considerations we as a community make about what is supported in fedora are 
different. In Fedora, we do worry more about supporting legacy platforms so 32 
bit support will go on longer. We still do have concerns about getting 
sufficient testing/qa resources to validate each platform.
