The diff calculation itself can require software that can't be distributed
to clients, because of licensing limitations, programming language, resources
or whatever. Note that it can be more than just a diff of text files. I
will use DeltaXML, for example, which is specialised in calculating the diff
between two XML documents. It inserts mark-up in its own namespace in the
resulting document.

The format can also be converted on the fly, depending on the "Accept"
request header. I could convert it to PDF, again with tools that are only
available on the server.
