Nobody is mentioning that there’s essentially nowhere you see the icon now without the name (internationalized) unless you’re already familiar with it, and pinned it to a launcher or something.
The first time you see most of them they’re on a page with screenshots and descriptions.
Nobody needs to know what the Word icon is before they know what Word is.
I have icons of apps I’ve used many times visible in a launcher, and I still have to think about which is which because they are so nondescript.
