As someone who has used that sort of software professionally in various capacities, I think "must-have" is a strong term these days. A lot of everyday software at work is no longer the massive-cost, massive-installation, licensing-headache behemoths of yesteryear. Also relevant, we do have some software along those lines on our Windows 7 machines that are about to run out of support, but the only way to get them on new machines running Windows 10 is to jump on the subscription bandwagon and deal with all the incompatibilities with the older but stable versions we've been using effectively until now.
