I’d say there’s a darn good point if Meta doesn’t want you to use one.
There used to be a great frontend for Instagram that was sued and forced to cease development when all it allowed you to do is browse Instagram on an account in this private frontend app.

Unless you have a reason to, I wouldn’t recommend a secondary profile as a daily driver yet. SMS doesn’t work perfectly and plenty of other bugs I’ve noticed which sometimes you have to switch to the Owner profile to access certain things, and sometimes things just don’t work in secondary profiles.
That being said, I’ve made it work. If you have a reason to use this threat model then do it.
