Correction. They are about how to begin with nothing but hardware and
source code and building everything from there. The bootstrap seeds are
there for those who opt not to hand toggle in their root of trust or
didn't want to do sed 's/[;#].*$//g' $input_file | xxd -r -p > $output_file
to build their root of trust (or some other equal method)

The requirements listed on your site are:
1) a POSIX-like OS on a 32+ bit CPU as a host for the building procedure
2) an ANSI (C89) compatible C compiler for the host OS
and your project builds a kernel (minix-vmd) which is written in C which
requires TCC (or GCC or Clang) to compile it.
So in bootstrapping terms, the only kernel that is bootstrapped that
matches your requirements is Fiwix and at that point minix-vmd is a step
backwards as Fiwix is able to build Linux and minix-vmd is not.
If you mean something else when you say bootstrappable and verifiable
builds; then perhaps you could be correct.
But as I understand the term bootstrappable, you are starting on done
and taking a step backwards and claiming to have gotten there first;
which doesn't seem fair to the dozens of people who spent the last 5
years actually bootstrapping everything.
