To be honest, I can count on one hand with less than all 5 fingers the number of people who I can recall that have inquired about the NDC in either Log4j's Jira or mailing lists. So the idea that somehow multiple stacks would be useful is surprising since the vast majority of users don't use the ThreadContextStack/NDC at all.

However, it does make sense that the ThreadContextMap (MDC) should support collections of values as well as single values. Although this implementation uses a Deque instead of a List it does fulfill that purpose. So when looking at it from that perspective it makes sense that keys in the Map should not overlap since it is an extension of the MDC.
