yes, see our Blackhat slides:

i saw BAP tries to implement some independent disassembler inside, which is
not right thing to do on engineering-wise, IMHO.

BAP can switch to use Capstone, which already has Ocaml binding in "v3"
branch

https://github.com/aquynh/capstone/tree/v3/bindings/ocaml

(we will release new version 3.0 soon with Ocaml binding inside)

yes, we try to do everything automatically, but the process of updating
Capstone is still partly manual.
this is the target, but not priority at the moment.
