It's possible that a junior dev who showed you the button might then joke to other junior devs about you not knowing. But a smarter junior dev, wise beyond their years, will realize it's just bullpoop trivia, one of thousands of bullpoops one has to pick up and later discard in favor of a fresher bullpoop, and be happy to help.
In any case, you, as an experienced person, should know it's just a different flavor of bullpoop, and not the most valuable thing anyone knows.
Your decision to stay in the loop, with the bullpoop that your team is currently enjoying, sounds like it might come in handy. But I wouldn't want anyone to ever feel humiliated over bullpoop.
A build process is one thing, knowing C++17 or rust is another. Knowing if refactoring all these templates structures was really worth 2 weeks is something that is hard to ask to a junior dev.
