Code addition to BASH

Running BASH version 5.0 on ubuntu 18.04

Hi I've recently made a code change to my local version of bash that I find
quite useful as a QOL update for scripters. I've added an environmental
variable called ITERMAX that allows me to see the size of the iterable
being used in the for loop. This means I can display progress bars and the
like similar to TQDM in python. Is this something that I could make a PR
for or is adding new shell variables considered taboo and to be avoided.
Thanks for your time.
