"Should there be a benefit to reaching level 40?"

#PokemonGO: I've been level 40 for a couple of months and, as most people know - it doesn't make any difference, except that you don't have a next level to work towards. My question is - should it? Should there be something (other than personal satisfaction and bragging rights) that you get for reaching the top level? If so, what? A few possibilities that have occurred to me:A second infinite incubator (my favourite idea)Increased spawn rates of rare pokemon (probably hard to implement)Automatic critical catch on common pokemon (to save having to throw multiple balls at Weedles)Special avatar items (an "I'm level 40" t-shirt anyone?) via /r/TheSilphRoad http://ift.tt/2uhJ0IE
