Currently to request a new cgroup fd (scope?) we must use a dbus call. This is slow and requires a dbus library or client. As suggested by @brauner here (https://github.com/lxc/lxc/pull/4287#pullrequestreview-1338699215), it would be nice if there were another way to make equivalent of the StartTransientUnit and AttachProcessesToUnit requests.

Define 'slow'. What benchmarks have you ran, on which kind of setup, and compared with what?
and requires a dbus library or client.
And? There's many available, in pretty much all languages.
Besides, there's already a different interface. You can create any scope units you like in /etc/systemd/system or /run/systemd/system and use them as you see fit.
