This is an important point. The std::expected proposal is a vocabulary
type that has not gathered much practical experience prior to being
proposed for standardization, unlike other vocabulary types like
std::optional, std::any, and std::variant. Boost.Outcome gives us
an opportunity to gather such practical experience, which can then
serve as input to the standardization process.

If our community goals includes being an incubator for some C++ library
proposals, then we should not evaluate Boost candidate libraries
strictly on the merit of whether or not I personally can use this
library for my own projects.
