Many things are fundamentally feasible. I see 2 things you argue for.

One is changing the caching strategy. I don’t think that’s wise in terms of load sharing, but certainly feasible on a small scale. In certain circumstances, it may be preferred.

The other thing is using older protocols and standards. The practical reason to do this would be to use existing tooling, libraries, code. I’m not seeing such opportunities. I’m not that familiar with these, but it seems like they would have to be extended anyway. So I don’t really see the point.
