The general consensus was that if we did bind mount /run/init to /lib/init/rw on boot (and vice versa on initial install, as for the othe locations), we would still need to transition from /run/init to /run anyway, so we might as well transition directly from /lib/init/rw to /run in a single shot. This is unlike the other directories, where the files are linked directly to their final destinations. The number of packages making use of /lib/init/rw is tiny (33), so it was thought that it could be removed fairly speedily as soon as the transition can begin. Of those, 16 use the sendsigs.d interface (trivial mv in postinst), 3 are just documentation/examples. The others can also be done fairly simply, while I haven't looked at all of them, most can simply just mv any files in their postinst (with a versioned dependency on initscripts).
