It's also more brittle.
Had a factory Winchester 7-08 cartridge split upon firing and got hot powder and gas to the face.

Have not found that to be true--especially because nickel-plated brass is just that--brass plated with a thin coat of nickel. There are NO cases made entirely of nickel.
Dunno why the 7mm-08 case you cite split, but it was NOT due to being nickel-plated.
