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.
