I'm not sure this is a major issue. End users are mainly concerned that when they wake up in the morning, lots of stuff hasn't moved. What it looks like and where it is to start with doesn't seem to matter as long as the UI is discoverable to some extent.

End users are also concerned with not being frustrated at every corner with arcane and weird UI choices or a user experience that plainly mirrors the implementation choices underneath. Worrying about whether features have been moved around the UI usually comes after they've already used a program for a while. There's lots of open-source software that, for non-technical end users, doesn't get to that point because they've ditched it already.
