I'm not sure why you say that. The above is a perfectly rational way of using
the existing printer control mechanisms (PPD's) to get a product that
can do what 99% of what people want, including making profiles.
It's mildly complex if you know nothing about color, but the defaults
will do reasonable things for most people, particularly in a home
or office context.

I've no idea why you are reacting this way. The above has been basically
"industry standard" for 10-15 years. The slightly more complex
version has "custom 1, custom 2" etc. settings, where the custom
profiles can be loading into the printer or RIP.

Typically sources that are tagged (either using PS CIE colors or
with PDF ICC profiles) will be treated the right way too.
Some even do named spot colors properly.
