Refined Wind

I was thinking of a way to specialize magic instead of researching everything.  For example, in my current 1.19 game, I had 2 air shards at the start, and chose to research the air magic book.  Now, I wonder if people like the idea of, after researching all those wind spells, to have a "refined wind" spell to continuously increase wind magic power and abilities, like how the other refined techs work?

This would give me a choice between specializing in wind, or getting a variety of spells.
