I've done it in the past (~2015). Honestly if Google locked me out of all of those other purchases it'd be great grounds to sue them. If everyone started doing this it would prevent them from doing this in the first place and may be additional fodder for (hopefully) continued anti-trust losses in court. If your life is tied to Google in that way then it's a risk no matter what you do and you should probably think about how to reduce that risk. I don't have anything other than purchases tied to my Google accounts anymore.
