Well, yes, if you want to lift more weight. However if you have a given weight and want to use less thrust despite being climb limited improved climb is a way to achieve that. The downside is that you use a lot of runway and get very high Vr and V2 which in turns increase runway occupancy time considerably, hence ATCs dislike of that practice, especially on crowded airports. By the way, V1 is not higher than normal and can even be lower since Vmcg is lower due to a derated thrust setting.
