Assaf Gordon has just detailed more reasons why af_alg should not be enabled by default at: https://lists.gnu.org/archive/html/coreutils/2018-06/msg00034.html
Thanks for the pointer. I was meaning to disable af_alg by default myself, as the arguments against it were pretty compelling (and Assaf came up with some more), and I have been hesitating syncing Emacs up to the latest Gnulib for this reason.
I suggest adding the URL to Assaf's email to your commit message, in this form: https://lists.gnu.org/r/coreutils/2018-06/msg00034.html
