I'm under the impression you can do most or all of what needs to be

boot, but aside from that, I think once you have possession of /bin
and /sbin, then assuming that /etc is not a mountpoint, I think most
other stuff can be delayed til the real init, always assuming that it's
easier to put stuff in the on-disk init than in initramfs.
Is that Linux that has been "improved" by turning /sbin and /bin into
symlinks? Or is it Debian? Or the systemd collection of distros?

Here's the story I read about /usr, and it sounds like the truth:
When people built the first Unix machine, the first disk,
containing /bin went full but they needed to add more files to /bin .
They decided to put them on the second disk which contained user data
and was therefore mounted at /usr. Hence /usr/bin. It was a technical
workaround for disk-size limitation.
Nowadays some distros got rid of /usr but still make it a symlink
to / because of softwares that rely on it. If Debian is now doing sort
of the opposite, it must be some trick. I've nothing against; as long as
you keep /usr, use it at your will; it's all about convenience tricks.
