That's true, storing in memory is still prone to XSS attack, it's just harder for the attacker to find it than localStorage.

Splitting the JWT into 2 cookies where the signature is in an httpOnly cookie, but the rest of the JWT is accessible to JavaScript makes sense. This means that the frontend can still access JWT except for the signature.

I think it's up to the website to determine what kind of attack factor that they're trying to mitigate against to decide whether they need the upgrade in security.
