This seems to have changed since you asked the question. jsakamoto has implemented NuGet package that allows you to keep your [Index] attribute. The only difference is order of variables; you can no longer have Order=0 as your last variable but rather do:

[Index("IX_TreeFiddy", 0, IsUnique = false)]
public string LochNessMonster { get; set; }

[Index("IX_TreeFiddy", 1, IsUnique = false)]
public int CentsGiven { get; set; }

Override OnModelCreating()

// Override "OnModelCreating"
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
    base.OnModelCreating(modelBuilder);

    // .. and invoke "BuildIndexesFromAnnotations"!
    modelBuilder.BuildIndexesFromAnnotations();
}
