Yes, support for using the Go implementation[1] with VpnService is in the works.
The same app will support both the native and userspace implementations. It will
prefer the native implementation if root access and the kernel module are
available, and fall back to using VpnService otherwise.

Using the native implementation has its own benefits. It will generally be
faster and more battery-efficient, and it supports having multiple tunnels up
simultaneously. VpnService only allows one VPN to be active at a time.
