Should we include theme block to developed theme for shopify store?

Hello, Shopify theme developers!

I have been developing a Shopify theme for theme store submission. Hope it will be submitted in the next two months. But, recently Shopify introduced theme blocks. Which is now in developer preview. I have tested it already. It will be a very helpful innovation for theme developers. My question is.

Should I add block features in my Shopify theme which will be published in the next few months?

Hope for a proper suggestion, please.

Thanks,

Zahidul
