I think the level scaling fits Golarion, since "becoming a god" is a semi realistic goal for someone to set for themselves :P

But people who want to play in grittier settings do use the proficiency without level rules, and from what I've seen all the major third party tools support that option. As a gm, It can be hard to balance for though! The +level to everything mostly serves to give your level 10 cleric a fighting chance on their stealth checks, and without that boost there are some actions some characters just can't perform.
