Wayland does not support screen savers: it does not have any provision that allows screen savers to even exist in any meaningful way. If you value screen savers, that's kind of a problem.
Why doesn't it? Well, I suppose the designers of Wayland have no joy in their cold, black hearts simply do not value screen savers.
They go on to explain that the security model of Wayland is better than X in this regard, yet instead of writing code to improve what they see as deficiencies, they bitch and throw insults.
This is not the way to effect change. Oh, you're being ignored? Maybe try having more emotional maturity than a 12 year old.
