I don't see any need to relax Ravenscar, because if you want to use features not allowed by Ravenscar, you don't have to restrict yourself to Ravenscar. It's a free choice. I suppose we could argue about whether the exact set of restrictions is appropriate, but the whole point is to be restrictive, so the run-time system can be simplified (as compared to a run-time system that supports full Ada). - Bob
