How much can hard-coded indexing be avoided in Julia?

I’ve noticed a trend toward Julia’s new keywords trending towards using keywords and functions instead of integer indexing in Julia. For example, first(array) instead of array[1], or eachindex(array) instead of 1:length(array). Is this an intended aim for Julia style-- to avoid integer indexes in code that can avoid it? How likely is it that in the future Julia code will not need to show its 1-based integer heritage in common written code?
