Reading this thread, I'm inclined to agree; rather than being too specific, we could note the security issues, as well as the potential impact on clients.

How about adding a paragraph to p5 5.4.2:

Servers are not required to return the exact range requested in a partial response, and MAY coalesce several ranges into a single response, to make delivery more efficient. Clients SHOULD NOT depend upon the requested ranges being returned as specified in a partial response. This includes the size of the ranges, their offsets, and their ordering in the response.
