The RIP is already deployed on several L2s.

I don’t think it’s reasonable to change it now and disrupt all the code that was deployed to take advantage of this new EIP and prove its utility for next Ethereum upgrade.
Furthermore, that reserved RIP range is to enshrine a range for experimentation for L2s so it’s fine for EVM forks to also use this knowing Ethereum L1s changes won’t reuse that range. See also: RollCall Breakout #3: Precompiles and the RIP Process
