Perhaps an example would help:

I cannot create a bad tree without --literally:

$ echo total garbage | ./git hash-object -t tree --stdin -w
fatal: corrupt tree file
$ echo total garbage | ./git hash-object -t tree --stdin -w --literally
fa2905d47028d00baec739f6d73540bb2a75c6f7

but I can use cat-file without --literally to query the contents and
information about the object as it stands.

$ ./git cat-file tree fa2905d47028d00baec739f6d73540bb2a75c6f7
total garbage
$ ./git cat-file -t fa2905d47028d00baec739f6d73540bb2a75c6f7
tree
$ ./git cat-file -s fa2905d47028d00baec739f6d73540bb2a75c6f7
14

As far as I could tell - and please correct me if I've misunderstood,
cat-file's literally is about dealing with unrecognized types whereas
hash-object's --literally is about both creating objects with bad types
and invalid objects of "recognized" types. This latter scenario is where
the option name "literally" makes the most sense.
