What is the "Amiga experience" for you?
From the top of my head...
* GUI available from boot
* graphical early startup
* boot without startup-sequence is still with GUI
* top screen bar with system information
* menu pops up using RMB
* multiselect from menu creates an event chain that is executed when RMB is released
* screens with their own unique properties, resolutions, colour depths etc, private to the application or public
* Save|Use|Cancel
Plus a lot more I am sure. My point is just that nothing technically stands in the way of reimplementing what I mean with "amiga experience" in a modern and secure way. Of course, amiga programmers see this entirely differently.
