Many people just read novels and won't care about the sleep timer. My first Kindle was a PW1, and I still have a PW3, DXG and K3. I've not felt the lack of any features in the last load of versions and don't need the Sleep timer, which should have been in all Kindles since 2007. Trivial code and useful to some people. Recipies?

There should be a Sleep showing open page option on all eink ereaders.Even the option to have it when off.a

I think that there is or was an ereader that does that. I think it added a notice that power is off. (Otherwise it could be confusing.)

The UI for changing the timeout in the context of keeping the overall UI simple, clear, and uncluttered is not trivial, but it would have been trivial to have made yet another undocumented searchbar command while they agonized over whether and how to add it to the UI.

(At least some) kindle users have been requesting that for at least 15 years. They have given the reasons, but I guess you weren't paying attention. Just because an application is useless to you doesn't mean that it is useless.
