Yeah, that makes sense.  AdaCore is trying to keep up with the Ada 2012
language, but of course there's danger: if ARG changes its collective
mind before the 2012 standard is standard, then AdaCore has to change
things, and people who choose to use those features will have to change
their code.  AdaCore's goal is to have Ada 2012 implemented properly
pretty soon after Ada 2012 is an official standard.
