I'm not a lawyer but I think that the above may be violated as MIT
requires the license to be included in "all copies or substantial
portions of the Software" [1], which includes binary forms, IMHO. At
least, that's the part that is not clear in MIT license as opposed to
BSL and Boost licensing policies.

In any case, one of the advantages of Boost so far has been a
relatively easy legal analysis for users as all libraries are under
BSL (it's not always been the case, but I think now it is). Adding a
library with a different license complicates use of Boost, especially
if there appear interdependencies between the proposed
Boost.Chrono.Date and other Boost libraries under BSL.
