Well, you are right. Lazyness...

I understood that:
Sonar runs in background as root. It "has a basic client process executable name check to prevent just about anyone to acess the data..."
If Situations is uninstalled and Sonar left in place, someone else (an app) called Situations could exploit Sonar "rootness".

I concluded that:
Well, who TF (else than goopple) would hack my phone? Who has interest to me? I do no banking or money thinks on my phone.
I personally see no big risk.
I don't trust trusts more than untrustable sources where sometimes genious is born of. or?
