Complexity is not an issue. It a very basic thing to do in these days.
UX might be a bigger issue, as it is harder to view this data in any device and still keep keys unaccessible by Google. But still not too hard. People use Whatsapp web in daily basis.
Main problem is the ML use for video feed to trigger some stuff etc.
Of course complexity is an issue. If users don't care about E2E encryption, why would Google spend more time implementing an E2E application?
