Sorry but this post makes zero sense.
Many apps (eg chrome) frequently fix bugs that are actively exploited in the wild yet have no public weaponized chain (sometimes for months).
The fact that there is no fully public weaponized chain does not mean it does not exist or that this bug is not as scary. It only means that it is not as trivial to exploit as log4shell/shellshock/etc.
According to cloudflare [1], it is being exploited in the wild.
It's like y2k. Yeah, there isn't much of a problem currently. We're patching before it becomes a problem. That's not Bot Who Cried Wolf*, that's responsible security. You don't have to wait for a YouTube tutorial on how to do it before it's something to urgently patch.
*My phone autocorrected to that and I'm keeping it.
