I think the comment you're replying to is referring to the pub/sub sections of the proposal. They don't explicitly mention events, but events are a subset of the publish/subscribe pattern.
The only "benefit" signals as proposed here give you is less control over the exact dispatch pattern of the graph, for instance things like debouncing, throttling, batching, etc etc etc. Aka all the things you absolutely must have control over if you want to make something resembling a high performance application.

Events don't give you any more control over those properties than signals, they just require more boilerplate.
