Then it's about aesthetics, not practicality. It's not a change that has to be made to make a better movie, just one that the current creators wanted.
"It won't hurt anything" is not a compelling reason to change things about a mythos. There ought to be something that the change brings to the piece.
A great example? When a black Nick Fury was first introduced in Marvel's Ultimates line. I'm sure there was controversy over that change, but that change opened the door to Marvel Studios casting Samuel L. Jackson in the role for the MCU. Samuel L. Jackson! Y'know who last played Fury in a movie before SLJ? David Hasselhoff! SLJ is an obvious upgrade.
Show me that a change made for diversity, or modernity or any other buzzword also improves the mythos in that manner and I'll stop objecting.
