Oh, don't worry about that. The inflated egos are distributed across all the musicians too. It takes a special kind of personality to achieve that level of singular proficiency.

I think it's one other reason to HAVE a conductor, is to have an ultimate authority on some matters where musicians egos get involved.

In many (most?) compositions, there are going to be some banger little licks in many different sections. It honestly kinda sucks sometimes when you've got one... but you gotta hold it back because it's still just a supporting component. To you, as the musician... you might fall in love with it, wanna push it, take the opportunity to shine and generate some goosebumps. And, obviously, since you're God's gift to the world, you SHOULD. The composer was WRONG to hit you with a mp. Maybe the composer's French Horns couldn't lead with it, but they never envisioned your talent.

The trumpets shoot you a look to calm down? Fuck 'em. They always get the spotlight.

Having a structure with an ego to rule all egos helps (does NOT eliminate) these kinds of things.
