Some people get enjoyment from looking at a lawn which looks like a bowling green. That is all well and good but just think about all the resources needed to achieve that. Synthetic fertiliser, selective weedkiller, iron sulphate, fungicide, wetting agent etc. Then think about all the fuel used to mow, scarifying and aerate.
I think you will find that the responsible thing to do is to let it do its own thing (apart from mowing). It will be much more rewarding to see a bee on the clover and realise you are doing your bit for the planet by minimising unnecessary inputs.
