I see. So, we have a distinction between implicit attribute derived from the
explicit one, and the implicit attributes conjured by compiler for the
compiler-generated code like special functions and lambdas. AFAICT we have no
good way to do so. E.g. telling apart inherited constructor with explicit HD
attributes and a default constructor with implicit HD attributes would require
more digging.
OK. Let's keep it narrow for now. We can consider relaxation if/when we have
actual use cases for it.
