Not necessarily. You should use a different account (preferably one with 0 transaction history, if no on-chain txes are needed) than your main financial account (and really, anyone not living paycheck to paycheck should have more than one of those in the first place. Cold/hot, have a separate one for any defi activities, use a new one for each L2, etc) Just like you may not have the same email for job applications and dodgy e-commerce, or bring all your cash and cards with you in a purse to the nightclub. (GP did say “shared across sites”, which should be a very deliberate decision and not the default. UX needs to improve to have better privacy by default. I could imagine Metamask defaulting to generating and connecting a unique address for each domain, requiring manually selecting accounts to have them shared)
