Exactly. Older DI motors like early BMW's that started adopting it before it was fully understood had problems with buildup so now everyone is paranoid and thinks that is the norm. The people selling the catch cans are going to fuel the paranoia more with "dyno numbers" showing why you should buy their product or your car will lose all its power and die in a fire.
In reality, I doubt we will ever see any buildup on DI motors anymore. They have been on Hondas since 2013 and we have many 200+k mile fleet cars with zero problems.
