Maybe another thought would be to have a section that actually describes
the extensions from the TS proposal (like the boost scoped exit compare) --
or did I miss it in the docs? My quick comparison looks to be mostly the
fd_deleter and unique_fd stuff and not so much in the core api?  Which are
pure extensions and could be clearly marked as such -- and could later be
converted to work with std::scope_* if people wanted?

And fyi -- if you're not aware of this improvement it's already in 26
working paper and gcc 14:
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2023/p1759r6.html
That might be motivation for including something like unique_fd at the
standard level as well.
