Rpcd services documentation

On Wiki we have a page with list of RPCD services exposed over UBUS and their description:
https://openwrt.org/docs/guide-developer/ubus

This is basically same as ubus -v list service .
The problem is that some methods/commands aren't clear by their name.
For example in the service state has params:
"state":{"spawn":"Boolean","name":"String"}

And I expected that this is method returns a current state of a service: running, disabled.

But from sources it looks like a completely different thing

Can anyone update the wiki page and add more description:
