 You don't think that the people who compile something relevant to the
world and relevant to them, know that this would be a good idea.

The best way to drive a bicycle is obviously with side-wheels, a helmet on,
knee paddings and to never leave your drive-way. Once the [a] lib is
compiled with Spectre-Mitigations, there is no way of "turning it off". In
reality the problem is highly hypothetical as most (Windows) Boost users
seem to prefer to use out-dated compilers [and out-dated Boost for that
matter] and will not [be able to] use these spectre-mitigated-libs anyway.
