Architecture of Azure VNet support for Power Platform

This does seem to conflict with https://learn.microsoft.com/en-us/power-platform/admin/vnet-support-overview#considerations-to-enable-virtual-network-support-for-power-platform-environment that suggests the entire platform is now bound to a single delegated subnet and that this will break Power Automate calls to public services.  However, it is clear and informative. A pity it does not show external interfaces to confirm this one way or another.
