The whole point of moving in V5 to a template driven display was to allow users to be able to make easy customisations – something which was not possible before without hitting core code. In your case you just wanted to remove the whole lot but actually the function you removed has a lot of power in enabling a user to change the way those stats look and display.
This was a contentious issue previously and we were forever having to say to users no – you need to change core code to do this or that. This is now rarely the case and hopefully we will do away with any areas that come to light where this is still not possible.
So this is largely an issue of not being able to please all of the people all of the time but we can now please a lot more people than we used to.
We used to have a ,lot of options that have been removed and another good result is smaller code and better performance. So afraid not – there is and will be no plan to re-introduce them.
And – using templates is also in keeping with the way that WP itself works of course.
