I don't understand why the entries file format is a problem here. 
If last week I checked out the TEST branch of my system and didn't touch 
the sandbox it would still be here today.
So why wouldn't it be possible to create that same sandbox with the same 
contents and all the revisions from last week today?

It could be usefull if you have messed up your system and want to go back 
to a week ago because you're sure it worked last week (but didn't tag 
because there was no release or anything.) Although I must admit that I 
have never had the need to do this myself I think that in a situation 
where it is required (when someone messed up the branch) it must be 
extremely frustrating not to be able to do it.
