Hi! You are completely right, I forgot to put it in my commit message. The "Compatibility" section of https://httpd.apache.org/docs/trunk/mod/mod_headers.html#header is already mentioning the >= 2.4.7 note so I thought to remove the duplicate.
If you feel that it would be better to restore it, I'll do it :) Thanks!
