This question (and the one above right now) are good points. GPG isn't really a killer feature right now. I likewise haven't needed secure e-mail in a while. I just happened to notice it when it migrated stuff over. I stopped using my Yubikey with gpg a while back.

All of that said - I'm replying to this message and not the other because there is one use for secure e-mail that may make a difference: DeltaChat. Deltachat uses autocrypt which includes your public key in headers. With autocrypt in place, Thunderbird can still read DeltaChat messages.

I'm not sure if DeltaChat will ever take off in large numbers but it seems like a decent option for secure chat/IM.

First time I hear of DeltaChat. Does it use email as the actual transport? Sounds prone to stupid latency. What's the benefit over Matrix?

[brnt]

It does, and the benefit is that anyone with an email address can already be approached via Deltachat, because all it does is send and receive email through the Autocrypt protocol, which gracefully degrades with clients that don't support it.

Gracefully degrading for clients that don’t support it is an un-goal of encrypted messaging.

[ekianjo]

You cannot read encrypted messages if you do not have gpg support. Not sure what your comment is about.

Latency is not that bad usually.
