Valid point. Same here.
For a lot of people, buying a hosting means to install those regular software like WordPress ( which runs around 1/3 of the internet ), MyBB, Xenforo, Joomla, Moodle, NextCloud and so on.
Now Ubuntu does take them through the first level. ie, get the OS installed. After that point the support for normal user ceases. An average user buys hosting and then he goes to cPanel to install those web apps.
I would understand when you say you do not need the panel flashing on your face once you install the OS. But let it be there ( a command far ) for people who would actually need a panel as an interface for their regular app install process. Won’t that be a win win for a lot of users ?
As for dedicating resources, every investment has its own returns. Currently when someone ask on those forums about which panel to use, most free panels are almost unusable due to security flaws.
