Setting to Show/Hide CW

I appreciate Content Warnings. They offer a means to be open but also sensitive to others. But just as Content Warnings offer a choice, they themselves are not a choice.
There appears to be no setting or option to Show/Hide Content Warnings. Having Content Warnings on by default is good. But why not make seeing Content Warnings optional as well? An option to enable/disable Content Warning would allow individuals to choose what experience they have. There are multiple levels of granularity throughout Mastodon (local vs federated, followers vs public, public vs private, show/hide explicit media, etc.). Why not make another preference to show/hide Content Warnings?
