This is my understanding as well. We do not really care as much about /EHa 
in libraries UTF depends on.

Unless someone from MS dev team can contradict this, I believe this is what
we need. As far as I know Boost.Build and according to my recollection, this
is was an intention form the very beginning.  Clients were required to be 
build with /EHa as well and that is enforced through the requirements 
section in Boost.Build rule.
