Can I know what do you lose by rooting?
It has been years since I last rooted a Samsung.
My last rooted Samsung was the N4.
Aside from Knox, what else?
My last rooted Samsung was a Galaxy S6, In those days the restrictions depended on the model, newer phones had more restrictions.
I remember that even S health was blocked and for some reason also incognito mode on the internet app, this is to say that Samsung is not very permissive on root and those restrictions depends by the Knox counter.
By the way you lost access to Samsung pay, private area and other annoying little things, also app from play store can have restrictions if the phone is rooted.
Nowadays i don't knows if somethings changed but remember that when the knox is tripped you can't go back.
