Are there any other utilities made to use with d-grid other than gap-#?

[daerogami]

In bootstrap5, btn-block was replaced in favor of using d-grid. Are there any other utility classes for something like row-templates for defining how many elements auto layout to a row or should I just be using a row/col "flex grid"?
The use of the term 'grid' for bootstrap's flex-based grid-system is maddening when grid is an established css concept. Makes it nearly impossible to search the docs for css-related grid information.
