We gave the opportunity to the backend to set its waits however it
needed (or not).

The general design principle is to get to the backend and give it the
tools it needs. Putting things in the midlayer only if you are convinced
that every single backend will need it, now and forevermore.

Your changelog fails to explains why you want to change the design and
make it midlayer heavy.
