Actually libxdg-vfs already provides such file-dialogs from the "host" 
desktop with the functions

xdg_vfs_sess_cmd_openFileDialog()
xdg_vfs_sess_cmd_saveFileDialog()

The problem is, that this will only work for standard file-open/save 
dialogs, but a lot of applications want to customize file-dialogs with 
their own widgets (previews, filter options, checkboxes etc...). In this 
case the coupling between the toolkit of the application and 
file-choosers seems too tight for defining a standard interface.

Perhaps a clean separation between presentation layer (toolkits, 
widgets, dialogs) and infrastructure layer (VFS API) would work better here.
