Actually, to see what to commit, you're supposed to use C-x V s 
(dvc-status), but you can't, since it isn't implemented properly in xmtn 
yet.  That's why xmtn-readme.txt currently recommends using C-x V = for 
this.

But your observation is correct that committing from the diff buffer is 
dangerous if the diff you're looking at is not the diff between your 
current workspace and its base revision.  I'd almost call that a design 
flaw in DVC's diff mode.  Committing from the diff buffer should 
probably be disabled altogether.  (It needs to stay until xmtn can offer 
an alternative, though.)

The reason why xmtn doesn't have a proper implementation of dvc-status 
yet is that xmtn doesn't have a parser for mtn automate inventory; I was 
hoping to be able to use a basic_io variant of automate inventory 
instead (since xmtn has a basic_io parser).  The code for a basic_io 
variant of automate inventory exists on a branch but has unfortunately 
never been finished.
