Well, yeah people will know that later

oh my god - the protections of yum are made with understanding
and not by blindly a random number

the existing protections finally have to goal to prevent whatever
you confirm is revertable by not remove rpm, yum and the running
kernel, systemd and so on itself

finally that means: whatever you do - even if you remove any
graphical tool you can still boot up the machine, login into
a console and "yum install" whatever you need

that is smart - alert based on a number is clumsy
i can see that number by myself at the bottom

on a system where i want to remove *any* graphical stuff
and anything but the core system i don't care about numbers
or cross-dependencies - the only thing i care about is that
after i have reduced the setup to a bare minimum i can
"yum install" whatever i need instead start from scratch
and insert the install medium
