Personally I don't agree.
What I will say is remotely locating switches is going to 'force' you to design the system layout better. And system layout is one thing that takes experience.
Some areas will still work better to have devices local, like hallways and stairwells on the 'out skirts' of the system, or an under-cabinet lighting switch in a task area of the kitchen, etc.
In a keypad control only system the keypad layout is crucial.
As far as cleaning people go, I give them their own 'Clean Up', and 'Goodbye' button. This way they do not have to interact with the lighting control system in any way, other pushing a single button when they begin their clean up.
Now guests can be tricky, because controlling advanced lighting can be difficult whether you're looking at a keypad, or 2 4 gangs stacked on top of each other, but simple, consistent programming is going to be the winner here.
Top button should always turn the lights On, and be clearly engraved 'Room On', 'Bright', 'General', etc. Bottom button should always turn the lights off.
For keypads in heavy flow areas with intersecting hall ways and stairwells that are keypad only control, there should be a keypad dedicated to 'toggling' all of these. A 4 button keypad that says, "East Hall, West Hall, Upstairs, Downstairs" is certainly easier than a 4 gang switch box for a guest.
Once we describe the benefits of whole home lighting control to people, they are generally fully on board, but 90% + of them seek us out purely because they want to 'clean up the walls'. Madness? Maybe, but to ignore this would be insane.
