Tried that and it works. The minimal public key of multiple UIDs written
as autocrypt keydata in my case is 15kB, quite large as mail overhead.
I guess there's no way to reduce that somehow? Command line gnupg has
filter options like
gpg --export --export-options export-minimal --export-filter keep-uid="mbox=foo at example.com" 0xKEYID
which ends up with 3kB Ascii-armored per uid.

Just due to rebuilding the header cache once without explicitly
switching it off for an autocrypt scan.

I didn't notice a negative impact on regular mail use.
OpenPGP/GnuPG encrypted mail preferred in all private communication.
