In the long run, I agree. However, adding this support brings the
diags up to speed with the "one mkey per subnet" model that OpenSM
currently (sort of) supports. We should do better down the road, but I
don't think this patch gets in the way of that.

I agree. I was worried that applying the config change without the
permissions change may open a potential vulnerability, but the answer
there is just to have the permissions change earlier in the tree than
the new parameter.
