I think changing the nsswitch.conf order is a really intrusive change that can't be done without a discussion.
But what I meant to say was that enabling the files domain without changing the nsswitch.conf order currently doesn't bring any benefit. This will change in future versions when we add a better API to control the local users, but at the moment, it is OK to disable the files domain at ./configure time. I'm sorry this was not mentioned more prominently in the 1.16 release notes.
