Don't like what other people are using 3d objects and flames for?, don't enable it.
As simple as that.

I've also been thinking about something like that. I think there's a way to make .obj items appear only in replays, but I'm not sure how to turn it on and/or if that suits your needs.
One way you could approach this problem would be if you could disable flames or 3D items or even sounds for certain players.
