Thanks, I see now.  That's still unfortunate, but not as bad as it
sounded.  Why does the IDE need to keep track of multiple formats
anyway?  Only one is being displayed..
The DSF GDB debugger uses the detail pane in the variables, registers, and expressions views to display the variable in all available formats at the same time.

There is a bigger issue here though.  The architecture of the debugger integration in Eclipse separates the UI code (views, actions, etc) and the non-UI code with an API that abstracts the details of the debugger back end.  However, GDB's design of the variable objects makes some assumptions about the presentation of the data in the UI, and these assumptions are making it somewhat difficult to create an efficient implementation of the  non-UI layer of the debugger integration.
