We have <https://apps.fedoraproject.org/koschei/>. Unfortnutely it's
only a wrapper above koji, so the granularity is a koji repository
creation that usually involves multiple changed packages.

It generates fedbus events. However I worry notification system can
recognize only the direct package owner. It cannot retrieve list of changed
dependencies and map them to their owners. (This is general FMN issue
not specific to Koschei events.)

It would. But there should be some limit. Rebasing very basic package
would spam thousands of people.

Also some rebases requires coordination between more packages. It would
be great if it were possible to specify that a rebase consists of
more packages.

Maybe each rebase should be built into genuine site tag and after
passing these tests and resolving/waving all issues, the package could be
rebuilt into real rawhide. And maybe it would create race conditions
between these genuine site tags and we would have to deal with rebasing
and serializing them. So maybe the current rawhide chaos is easier to
manage.
