No, my intention is not to make requested-by (or its variant suggested-by)
official.

The issue is that, when it is said there that
"all except CC/Reported-by/reviewed-by", plus considering other
other hunks of this patch like:

        "is one of only three tags you might be able to use without
         explicit permission"

You're basically requesting explicit permission for any "non-official"
tags as well, including reviewed-by. This is not what it is wanted here.

See, if we run:

        $ git log --pretty="%b" 1da177e4c3f4..v6.13-rc1 |grep -Ei "^[a-z\-]+: 
.*@.*"|cut -d: -f 1|tr A-Z a-z |sort|uniq -c|wc -l
        764

There are 764 tags (and 764 ones, for the last 2 years) that are e-mails 
r e-mail related tags. Among them, there are several ones that comes
from the message-id (which may disclose the hostname that was used
during patch development).

The top 20 being:

From that, besides the 3 you mentioned, at least 5 don't seem to require
an explicit ack: author, from, to, requested-by, suggested-by.

Thanks,
Mauro
