The important part is whether they can associate two identities together. If you use a shared Google login for everything you're doing their work for them.
For me the bigger issue is privacy. If you're using Google to log into everything, Google gets to add all of that activity to their profile on you, and track you as you use every website you go to. No thanks. Google doesn't need to know I'm buying a pizza tonight.
IMO ask people you know to tell you how you honestly come across. Yeah they like you and won't want to hurt you but as long as they aren't completely blowing smoke, you should get enough hint of anything glaring. The little things they sweep under the rug are probably nothing to really worry about.
I guess I don't see it because the posts are deleted. Ultimately I think people should be able to delete their own posts, so I think you have to try to make it part of the rules or etiquette that the community enforces
When I started out with Graphene, I had a non-owner profile as my primary day to day profile and had trouble with receiving text notifications, but also having to switch around profiles often eg. to change various settings. Later I switched to using the main owner profile as my primary profile and it fixed my issues and simplified things greatly. I still use alternate profiles for a few things like my banking app, and anything requiring Play Services.
If sounds like you also not using the owner profile as your daily use profile. Perhaps this approach could help with your alarm issue.
I've had zero apps not work, including my banking apps.
