Release notes: Changed When replying to a mailing list, reply will be sent to address in From header ignoring Reply-to header

This is a bad idea! A mailing list's default behaviour is to reply to list, not the individual sender. Mailing lists will disappear when nobody replies to the list. It is very rare when I want to reply to the original sender, mmailing lists are a common places of community knowledge, it is advisable to discuss through the list instead of private conversations due to this knowledge. Where can I switch off this thing to restore pre-52 behaviour? It is very annoying that I accidentally reply to an individual instead of the mailing list! Tried to search about:config, but found nothing. Ignoring reply-to breaks RFCs, it would require a configuration switch to restore normal functionality!
