First, you forgot the signoff, but you have addressed that already.


Second, I thought at first that it would be good for the patch to also
simplify %feature hash, using "'default' => 1" instead of current bit
convoluted "'default' => [1]", at the cost of bit more code for
defensive programming.  But now I think that if it is to be done,
it should be put as separate patch.
