An extensive discussion, mostly on the hotspot-dev list [1], resulted in
a change to JEP 248 to note that there is some concern that G1 might not
be ready to become the default, that making it the default now will
allow us to get more feedback on it, and that if it proves to be not
ready then we'll revert the default to the Parallel GC in time for JDK 9
GA [2][3].

With that, I think your concern has been addressed, so I've targeted
this JEP to JDK 9.
