Yeah, it isn't really a back-door. A back-door suggests you aren't being made aware of it, and right off the bat, you will / may be prompted to authorize corporate management of your machine (or click the 'Allow management of this app only').

The result of allowing machine management means the company can dictate if you are required to install certain updates within a specified timeframe, update software that is out of date or contains a known vulnerability, etc. Whether at the document or machine level, this management can also mean that you get information rights management applied to your documents by default, so you need to ensure you change the sensitivity label to whatever the "non-business, don't touch my stuff" option is, provided your company has configured one to begin with.

It is not the boogeyman, but nor is it something to be taken lightly.
