> What typical use-cases do these particular features have?
For the io logs: auditing. And in some cases such logs are necessary for compliance reasons.
For wildcards: allowing to run a command, but only if they supply a specific option that makes it less dangerous. Now, you do have to be very careful when doing that, but there are cases where it is useful and explicitly listing every variation of options that is allowed isn't practical.
I also forgot to mention sudoedit. Although, making something similar for doas would be pretty simple, so I'm kind of surprised there isn't something.
