This is one of the things iOS's Lockdown Mode does. I wish the features of Lockdown Mode were able to be enabled individually instead of a single all or none option.

I’ve turned on lockdown mode while this CVE insanity is going on. It’s far less disruptive than I expected. The only thing I noticed missing is web gl is disabled.

Your link doesn’t say anything about PDFs. And if I remember correctly it only disables PDF previews in Messages. This means if you have a zero-click exploit now it becomes a one-click exploit. I fail to see how that’s relevant given the article is already demonstrating a one-click exploit.
