Considering that I doubt most normal office-user people even use features in Word other than changing fonts etc I doubt that will be a big issue anyway.
It doesn't need to be "most". "Some" or even "a few" can be enough to make a hell of a mess if those few have created documents that are key to the business in one way or another (proposals, end-user documentation, etc). And there are the other components to the suite like Powerpoint, Excel, and Project to consider.
Not sure if you've worked in an office recently, but on google workspace I (we) use very regularly:
- Group Editing - this ones hard to get right - Reviewing Tools - Automated document generation - Embedding of data-backed images from 3rd party tools
Looking at my wife who works in government, they use it even more heavily, with a lot of complicated formatting, numbering, standards etc going into each document, plus OneDrive collaborative features on top of that.
I suspect office-user people are where most of the features get used. Agreed, most people only use 15% of the features, but which 15% that is likely changes quickly person to person.
