@indraraj26 we did discuss similar possibility for computed but didn't want to introduce new APIs without clear indication of a common use-cases.

Which brings me to the question: what would be use-cases that you are trying to solve?

Examples are already available in the link. With this read/write you do not have to write separate listener for (change) then update signal

Those are examples from knockoutjs so the context is different. I wanted to understand how it would make your life easier in the context of real-like Angular code.

Could you share a stackblitz with the exact scenario that makes you write more code that you would like?

Again, I'm happy to explore the idea of computed signals that can be written to as well - given enough important use-cases. Going to close the issue for now but will keep an eye on the usage patters.
