LOL
Your argument of "yeah, but playing as a bunch of lolrandom morons (no judgement) means infiltration is almost impossible" might not hold as much water as you might think. Really go back and read what you wrote there...one player literally saying "we're the baddies!" out loud and another, knowing there's a chance of literal chaos being unleashed any time they cast a spell, casting a spell at a time when the very last thing the party needs is to unleash chaos...can you see why self-sabotage is not the counter argument you appear to claim it is?
By the same token, Pass Without Trace isn't a very good party stealth tool because the Barbarian keeps standing in plain sight.
In a game where the party is a goofy parade of rare and exotic races and classes, using features and spells that make them stand out of a crowd, yeah, an infiltration and espionage focused character is going to spend a lot of time pinching thr bridge of their nose and visiting herbalists and alchemists for tonics for their migraines. Notoriety and reputation is easy to gather when you're the exception to the norm; there's a reason celebrities seem larger than life. Power, importance and position don't necessarily go hand in hand with celebrity though, even in a world with mass media, let alone one without. Some of the most influential people in the real world are faceless suits or uniforms and The Winter Soldier, while we're told is supposed to be one of the the Marvel universe's premier spys, is practically a poster boy for "hey look at that obvious and easily identified person standing out from a crowd by having a massive fight in a public place with little to no regard for preserving his cover".
