There have PruneDistanceFlag and PruneBlocksDistanceFlag, so i think we don't need this.

bsc-erigon/turbo/cli/flags.go

Lines 94 to 101 in c45c84c

	PruneDistanceFlag = cli.Uint64Flag{
	Name: "prune.distance",
	Usage: `Keep state history for the latest N blocks (default: everything)`,
	}
	PruneBlocksDistanceFlag = cli.Uint64Flag{
	Name: "prune.distance.blocks",
	Usage: `Keep block history for the latest N blocks (default: everything)`,
	}

I think this can reduce the length of the startup parameters. This modification can make --prune.mode=minimal --chain=bsc equivalent to --prune.mode=archive --prune.distance.blocks=90000 --prune.distance=90000 --chain=bsc
