There must be someone with a conduit into the Boeing B737 development department who can ask 'the horse's mouth' and relay the words of wisdom to us all: the technical reasons, not just a "we haven't thought about it too much so think it's not for best......"
There are other 'not recommended' techniques mentioned which I've not fully understood the thinking behind. I've tried their use in the sim and they worked fine and made life easier in an engine failure case; and I failed, via the in-house tech dept, to find out the reasoning. The tech dept wasn't interested and so didn't pursue the issue, just forbade it.
