As Danilo points out, we want to foster healthy debate and land
on whatever comes out of that. Not just by counting noses. :)

Alex's latest response[1] does a *much* better job than mine, in
explicitly highlighting what we get out of this. (It arrived a bit after
your response here.) Please take a very close look at that response and
see what you think.

The patterns in these page tables are not a new thing, and Rust has
language features to help express them.
