Why all phrases cant be edited in frontend / why we dont have list all of the phrases?

Yeah, title says it all.

I love the feature how to edit phrases in frontend, it is super simple! But for some reason all the phrases cant be edited there, why?

And because they are not editable in frontend we should have comperensive phrases list. Some of the “hidden” phrases can be found here with search, but not all of them. I dont want to create ticket to Support, it takes too much time, and I don't want to use their resources for “nothing”.
