Building Serverless VPN, among the most recent work is an open source iOS app: https://UpVPN.app/ios
This juxtaposition creates a somewhat amusing contrast.
It’s a new idea bridging two existing concepts serverless and VPN.
While serverless is an implementation detail to reduce cost, it is also a core user experience when they click the switch to be on.
The section “Serverless! How?” that you referenced, aims to illustrate what a user will experience.
I consider it to be a minimal learning curve, just like all new technologies.
That said, how would you go about best communicating it?
