Description

It's so much easier if you can safely tell people to trigger a full GC to discover their live set (see CASSANDRA-3574), instead of explaining the behavior of CMS and what the memory usage graph looks like etc etc. Shipping with -XX:+ExplicitGCInvokesConcurrent means this is by default safe.

For people that have special needs like some kind of rolling compacting GC with disablegossip, they are special enough that they can just change the VM options.
