Agree. I don't think this is any good idea before we depend on version >=
1.9.0.
Another limitation that make this challenging is that the open FileGDB API
only supports FileGDB of version 10. According to my knowledge, ESRI tend to
not support older GDBs "out of the box" each time the upgrade a minor
version. Additional compatibility layers are required, or upgrading is
necessary (which all requires a commercial license).
This is the reason why I what to support FileGDB through dynamic linking og
both ArcObjects and the FileGDB API, much in the same manner as the ArcSDE
and Oracle plug-ins do. This allows us to support the same FileGDB version
as the installed ArcGIS runtime environment, and if available as a native
library, any FileGDB version supported by the open FileGDB API.
