I'd love to see those encryption usability issues fixed, but I do want to say that e2ee on Matrix is less bad than on anything comparable (like OMEMO on XMPP). I like XMPP because of its speed, but you really can't combine OMEMO and multi-device unless you just don't mind having parts of your message history unreadable on some devices. The key backup and session validation in Matrix/Element usually solves this issue.

Unfortunately, the complexity means that even other Matrix clients that support e2ee don't support key backup and session validation, which means you either stick to Element on every platform, or live with the same history issues as on XMPP.
