On the latter, you turn the focus ring and it has a set and finite movement. It's instinctive. The more you use it, the better you know where closest focus is and where infinity is. It has 'end stops' - the points at which it won't turn anymore.
I can relate to that. D FA 50/2.8 has the AF system that allows full manual override. The downsize - it will rotate beyond infinity and closer than the closest focusing distance.
And I totally agree with your sentiment that focus by wire is simply different mechanical realization of the same electronic switch (such as rocker switch)... I believe it may be possible to make it "closer" to the good olde mechanical focus ring, but it would probably be way out of the target domain, so to say.
