According to the docs @ https://getbootstrap.com/docs/4.3/utilities/text/#text-alignment, we can create breakpoints for aligning text i.e. text-left, text-sm-left, text-xl-center etc.

There is a text-justify class for all breakpoints, but there are no individual break points? Why hasn't this been added with the other alignment classes?

For example, on mobiles a block of text looks better to be centred, but anything larger should be justified. This could easily be achieved by using text-center text-sm-justify, to work along the lines of all the other alignment classes.
