Samba 4.16 has been EOL since 2023-09-04[1]. We should start deprecating it once we switch the default to a newer version. [1]: https://wiki.samba.org/index.php/Samba_Release_Planning
Several ports rely on the deprecated port net/samba416, i.e. devel/gvfs net/pecl-smbclient@php82 multimedia/kodi print/cups-smb-backend security/gvmd to mention only a few directly dependend ports, but especially devel/gvfs has a hurtful impact on other ports, i.e. graphics/inkscape deskutils/nextcloudclient x11-fm/thunar x11-wm/xfce4 x11-wm/xfce4-desktop or from net/pecl-smbclient www/nextcloud-calendar www/nextcloud-contacts security/nextcloud-end_to_end_encryption www/nextcloud net-im/nextcloud-talk or security/gvm due to security/gvmd and so on. Setting net/samba419 as the default samba version in make.conf results in lots of failures even in a small poudriere setup.
