These indexes are NOT required for Masternodes aka EvoNodes running platform, two observations.

1. A Masternode does not run a wallet at the same time, this is intentionally not a possible configuration.
2. None of the RPCs (and I checked them all) require any special indices and the one that does getaddressutxos is for nodes running wallets, refer to 1.
