Ok, let me tweak the example a bit:

void foo()
{
     assert(__ctfe);
}

unittest
{
     foo();
}

druntime catches _all_ exceptions:

https://github.com/dlang/druntime/blob/46867186035fdf5ec2596efbb770627518ff0919/src/core/runtime.d#L617

Regardless if anyone does it or not, it's still a breaking change. Then 
we can of course argue the impact of the breaking change, how much code 
will actually break.
