The great directors and writers know this.
And this is one of the big reasons the x-men movies didnt get all the praise all these other franchises since the 00's have gotten.
Well in a large ensemble it's a tad unrealistic for every character to get their own solid arc. Unless you're talking about something like LoTR, with 3 x 3 hour movies.
Plus I do not think that it all depends on an arc, especially for the supporting characters. Sometimes the presence and sense of personality that an actor brings to the part can be enough to make them memorable.
