I'm going to put some words in explaining why I don't want to use base

preferring base classes?
Not preferring, but having it as an alternative. Mainly for 2 reasons:
1 - data classes allow one to type in classes very quickly, let's
harvest the benefit from that.
Typing a decorator in a shell is much less comfortable than using
inheritance. Same thing about IDE: all current ones have snippet with
auto-switch to the class parents on tab.
All in all, if you are doing exploratory programming, and thus
disposable code, which data classes are fantastic for, inheritance will
keep you in the flow.
2 - it will help sell the data classes
I train a lot of people to Python each year. I never have to explain
classes to people with any kind of programming background. I _always_
have to explain decorators.
People are not used to it, and even kind fear it for quite some time.
Inheritance however, is familiar, and will not only push people to use
data classes more, but also will let them do less mistakes: they know
the danger of parent ordering, but not the ones of decorators ordering.
I also feel inheritance is more intuitive (and easily entered), but missed the
reason it wasn't chosen. ;)
