You could use inheritance. If the condition is true, you inherit from a struct that provides the data member, otherwise you inherit from a struct that does not. Ugly, I know, but it works if inheritance is an option for you. That’s what I’m doing, but as you say, it is ugly:

template <typename Policy> using proxy_base_t = std::conditional_t< has(Policy::requirements, features::raw_access), proxy_raw_access, proxy_nodot<Policy>>;

template <typename Policy> class proxy : public proxy_detail::proxy_base_t<Policy> { … };
