The two options you describe are the only ones which come to my mind
right now as well.

It is on purpose that there is no such API yet, since with
load-balancing a compositing-only node as such does not exist. A node
which is only compositing for one frame might contribute to rendering
during another frame.

_If_ you can do the lazy initialization cleanly, I would go for it
since it is the most flexible solution. Otherwise hard-coding node
names is an option, although you might need to change this in the
future.
