As per 8.1.2.5, To allow for better compression efficiency, the Cookie header field MAY be split into separate header fields, each with one or more cookie-pairs.

After some tests, it does positively impact compression rate and reduces the eviction rate on the dynamic table (flavor may vary depending traffic patterns).
