And it still involves some significant trade-offs in terms of functionality: Potentially worse (spam) filtering and no full-text search unless you keep a full local copy of your mails around (which is rather unreasonable on a phone and impossible with webmail).

All depends on your threat model. I would never expect to receive sensitive information via email in 2021 when there are protocols like Matrix available. Even my bank and utility providers only send me email notifications telling me to login to their platform to view sensitive information. At this point, other than select business communications, email has been relegated to a two-way notification system for most people.

Sure, I send a lot of emails, but likewise, if I had anything worth keeping private, I certainly wouldn't be sending it in an email, even an encrypted one.
