I had to ask ChatGPT what you meant by MVP. Minimum Viable Product?

So this series just creates a new address space and then ensures that
sensitive data is not mapped there? To me, that's a proof-of-concept,
not a bit of valuable functionality that can be merged upstream.

I'm curious how far the first bit of functionality that would be useful
to end users is from the end of this series.
