This is definitely where I would this pattern - MS Office 97’s customizable toolbars necessitated this model where every single thing you could do in the application had an icon.

It then got copied into Visual Studio, where making all of the thousands of things you could do and put into custom toolbars or menus have visually meaningful icons was clearly an impossible task, but it didn’t stop Microsoft trying.

I assume Adobe, with their toolbar-centric application suite, participated in the same UI cycle.

By the time of Office 2007 Microsoft were backing off the completely customizable toolbar model with their new ‘Ribbon’ model, which was icon-heavy, but much more deliberately so.
