I once was on the same page, but have since changed my mind when I
realized that the other way round, i.e. /{bin,sbin,lib} -> /usr/...
actually to me makes more sense, as it keeps all the "static" files
that are part of the distribution neatly in one place. The only other
significant things left in / then are site specific configuration in
/etc and, if not already placed in a dedicated file system, persistent
variable data in /var.

This allows e.g. for things like rendering the entire "static" part
of the system effectively immutable simply by mounting /usr read-only.
(And yes, referring to other sub-threads, in that case one would
indeed have to mount /usr by means of an initrd, which is neither
brain science nor rocket surgery.)
