The "even more privileged" workarounds have been working in launchpad-buildd for a while now. We can't use unprivileged containers for various reasons, for example because one of the categories of builds that needs to install snaps sometimes is live filesystem builds, and those do various things like mknod that'll never work in unprivileged containers.

Of course, launchpad-buildd is somewhat special in that it typically only runs a single build before shutting down the VM, so I can imagine that there might be some isolation failures that are a problem in general but that don't affect us in practice. Please don't outright forbid privileged containers though, as we don't really have a good alternative.
