Sure, but doing "git checkout -f some_ref" instead of "git checkout 
some_ref" isn't really _that_ annoying, is it? I think, people (because 
of not having read/studied the .gitignore semantics well enough) having 
their files being overwritten _without realizing it_ is a bigger danger. 
But obviously there is a bit of treading a thin line here.

If we feel thrashable is stretching it too far (which I don't think it 
is), we could add a "core.ignore_files_are_trashable" setting that 
brings back the old semantics, for those who have a strong feeling about it.

It's also quite possible to do it the other way around - i.e. set 
"core.ignore_files_are_trashable" to true by default, and let the "new" 
behavior be opt-in. However, this might "miss the mark" in that those 
people who would really benefit from the new semantics might miss this 
setting, just like they could risk missing the "precious" setting.

(I also think "trashable" sounds better and is more clear & precise than 
"precious", for whatever that is worth.)
