My best guess right now is that both class allocators and the

Yes, just use emplace() insead of placement new.
GC-less allocations however is up to you, either malloc/free,
std.experimental.allocator or any other way. You can make your
own smart pointer struct to handle this automatically, or better
use community packages such as 'automem'.
As for the message it is possible that this part of the reference
compiler was already passed deprecation period and should be
removed but was completely forgotten.
