Is bloat in std::unexpected expected?
There are several implementations of compact optionals, see https://github.com/Sedeniono/tiny-optional, and related work & reddit thread.

tiny::optional – a C++ optional that does not waste memory
tiny::optional is a header-only C++ library for x86/x64 intended to be a drop-in replacement for std::optional with the twist that it does not require additional memory for bools, floats, doubles and raw pointers. For example, a std::optional has twice the size of a raw double because of 7 padding bytes after the internal bool. These wasted bytes can have a notable impact on performance in memory bound applications. On the other hand, a tiny::optional has the size of a double by exploiting unused bit patterns (i.e. by exploiting platform specific behavior).
