Oh, I understand now. Using a file is the preferred way since it is more efficient. But if a meta tag was added as part of the contribution, it might cause confusion for those that already have that tag or file in place. I don't think google would care if there are two entries but there's no reason to add extra entries. Plus, if it were added to Header Tags, it would be in the includes/header_tags.php file, which means the tag would get added to every page that uses Header Tags, which is not needed. You can edit the includes/header_tags.php file if you want to add the verification code yourself though. But that would be the same as editing the index file so nothing would be gained. Or a configure setting option could be added to where you could set it there and then the code added to display that, but that seems like a lot of work for a one-time change.
