I don't know, I'd say Signal is perfect, as it maximizes "privacy times spread". A solution that's more private wouldn't be as widespread, and thus wouldn't benefit as many people.
Signal's achievement is that it's very private while being extremely usable (it just works). Under that lens, I don't think it could be improved much.

Exactly. Plus it basically pioneered the multi-device E2EE. E.g., Telegram claimed defaulting to E2EE would kill multi-client support:
"Unlike WhatsApp, we can allow our users to access their Telegram message history from several devices at once thanks to our built-in instant cloud sync"

Signal just did it, and in a fantastic way given that there's no cross device key verification hassle or anything. And Telegram never caught up.
It's not perfect simply because it's a mobile-first app. That's Signal's main problem.
Yeah, most people don't even have a phone, let alone use it as their main method of communication...
