The encryption additionally prevents:

- gmail replacing/MITMing embedded links
- gmail adding EXTERNAL SENDER to subject lines

among other things. All of them things that happen today.

Those things are great for non-mailing-list emails but for mailing lists
it's just insufferable. Anti-spam is great but we need anti-anti-spam if
we want mailing lists to survive into the next 10 years.
