Yes for a new trait, for the reasons:

1. POD status is affected by a number of characteristics. This would all have to 
be rather carefully done to ensure an exact match with the compiler.

2. There are many discussions here about changing the definition of POD. The 
likelihood of changing the compiler, and then neglecting to change the Phobos 
version or not updating the Phobos version correctly is high.
