So next who ever asks this question must now have root access to /etc/default/grub/ (distribution specific path) and set some flag that indicates that it already asked the question (it cannot just scan the boot flags since the non-existence of the flag could be both that you answered "yes enable" or that you haven't answered it yet).
So now what to do if the performance penalty goes away, shouldn't this software somehow handle it and reenable it to increase the security. And so on.
Yes a lot of stupid ramblings, but the original premise was "how hard can it be" and I would say that it would actually be quite hard and complex if you don't want to be trapped in some odd behaviour. So much simpler to just tell the end user to add "spectre_v2=off nopti" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.
But "whah, whah I don't want to have to use that hard to use terminal" well then perhaps you also might be precise the kind of user that really needs to have this feature enabled by default.

"hostilely" - you mean I call BS what I see BS? Sorry, I can't restrain myself when there is a lot more idiots on the Internet than of reasonable people who actually know something. You see, IRL idiots are at least prudent enough to remain silent - not so much on the internet where absolute most people are hidden behind nicknames. And, also when you're polite, your reasoning will be simply dismissed.
Opinionated, you mean "knowledgeable"?
"ironically, attention-seeking" - never thought about that actually. And if I really were, I'd find another avenue. And being notorious among Linux users? WTF, are you even serious? It's like being famous among hobos. Yes, it's a sort of insult but your reply was a pure insult in the first place because it egregiously misrepresented facts.
Still, fuck off. At least I made Linux notice the issue. You, petty fuckers at Phoronix, may keep on upvoting your insults towards me as much as you want. Most of you bloody suckers haven't done anything for Linux or open source in your entire useless life and you hate everyone with a brain who notices issues with your OS which most people in the world couldn't care less about.
Well, thank you.

Oh wait, the jam exploit...
