This doesn't exactly inspire confidence.

When a library enters Boost and is distributed in Boost releases, there's no
longer any point of it duplicating Boost functionality under the hood
(without a very good reason); while not requiring Boost is understandable
for standalone use, in a Boost release Boost is by definition already

In addition,

carries the unfortunate implication that Outcome in Boost may be, similarly
to Boost.ASIO, a second-class citizen that may lag behind the "real" Outcome
where the real development occurs.

And finally,

> then Outcome would gain a Boost.Build veneer...

libraries are much easier to review if they are already in their final Boost
form, ready to be copied into $BOOST_ROOT/libs/$library. It's understandable
that people don't want to invest into that final step until the library is
accepted... but it should also be understandable that going that extra mile
is a sign of commitment that speaks positively about the author and can
therefore tilt reviewers toward acceptance.
