Maybe, but then we would have to rewrite the entire kernel. There are many
cases like this (not only in the action code) where units are accessed
directly, if it is safe to do so. In this specific case, it doesn't matter
if we access real units since enemy units are ignored and information about
them therefore cannot leak back to the interface or the AI.

I agree that a pure view-based kernel code might have some advantages. But
we are a far way from there.
