SNTP client is in the system package. Since both others are optional, why would you want that? So that you can not disable or uninstall them? Not everybody wants the NTP or DHCP package on a specific router.
its simply because you failed to read my post in first place, where i explained thats unmanageability by both webfig and winbox - make it virtually unusable for newbies and soho users.
and allso thats simply illogical. why not make half of other ROS features absent in Winbox like SNTP ?
also thats not a good/meaingful exmaple
"not everyone" wanted SMB/CIFS file sharing, "packing", "socks", "TFTP", netflow and most importantly Web Cache, it it IS part of System package anyway, so i think /this/logic didn't apply here, sadly.
