What if browser extdata could be modified in some way to prevent the nag and let those users browse freely? If other way of running homebrew is used, you could potentially un-block those systems.
It's a shame anything of those could be actually done, but I think it's a valid point.
Wouldn't it help if we could somehow remove what's making the nag in the first place perma? Like an installer (eg. Themehax or OOTHax) but one that changes/deletes whatever is causing the nag. Although I guess then if we had such a thing we wouldn't have a problem with exploits being patched.
At the very least if you do that, then you've got a backup in case something goes wrong again.
