since the changes don't persist across reboots, you can try them and if you don't notice any downside, set something up to change them for you permanently.
PowerTOP tops up to 2.1

Powertop mostly just makes me feel that my OS could have had good battery life but doesn't.
A doc blurb about the tradeoff for each toggle might go a long way though. Or if all of them have a "slowdown" worst case, one global blurb explaining that they're all safe but may cause performance decrease.

So you need to take a risk at some point, and if the system crashes, don't use that option any longer.
These are the sorts of possible problems (along with the performance issues) that make it so that Fedora doesn't default all these things to the most power saving mode.
Some people seem to forget that the best way to have a computer save power is to never buy it in the first place. Computers are purchased to get things done, and that requires using power. How much power should be used depends on how valuable the result is to the person paying for it.

no way I'm getting near that, basically. would rather just have bad battery life.
