Does the Manual Reward Claims (MRC) allow for simpler crunching and more GRC transactions without adding additional staking nodes to the network?

One of Gridcoin's strengths is that it is more energy-efficient than Proof-of-Work-based coins (e.g. Bitcoin & Ethereum today), but a distributed Proof-of-Stake coin (like Steem, or soon, EOS) might leapfrog Gridcoin to be a more environmentally sustainable option. Can MRC help Gridcoin minimize its environmental impact?
