Examines making objects appear across process boundaries and shows why std::variant and C-style discriminated unions fail: huge autogenerated headers, bloated memory because unions size to the largest message, and surprising compile-time blowup when files hit millions of lines. Demonstrates that P0593 lets code treat bytes-as-objects safely for trivially copyable types, explains the missing library piece start_lifetime_as, and reports that with those constraints the byte-buffer header parsing approach works without undefined behavior.
