OpenRC is still more difficult to write init scripts for than systemd; and offers less flexibility in scheduling inits. For example, I can add a 'before' clause to a custom systemd service unit, and I don't need to modify the subsequent units to depend on my custom unit. This is especially useful when you want a custom forking or oneshot service to reliably run before a standard service shipped with a package in your distro.

In a similar vein, systemd targets are considerably more useful than sysv/OpenRC runlevels. A typical sysadmin can read a couple paragraphs of manpage and set up a new target (analogous to runlevel) in systemd; and it can be used for debugging or recovery in the same fashion that runlevels are in other init systems.

On top of this, there are powerful system services developed in tandem with systemd, in the same repository, which offer well-integrated standard alternatives to things which were superficially different on ever distro only four years ago.

Less flexibility how? Please be specific. Before clause exists in OpenRC and is typically rarely useful.

The things it has are incomplete and too integrated, making them hard to replace with working alternatives that do what you want.
