If we do the chemistry and figure out the mechanism and it looks like it happens all the time, then that tells us one more term in the Drake equation and gives us a reason to go check out the exoplanets.
I think we are going to find that the preconditions for life are quite common. The way solar fusion and supernovas work, what atoms are produced, The distribution of material and of those atoms within an accretion ring... if a planet forms at the right distance, then it will have the mix of chemical precursors.
Honestly I suspect the only thing that makes Earth rare is our freakishly large moon. If we can ever prove that life is viable on a timescale of eons on a planet without such huge tidal forces pumping the biosphere, that will be a revelation.
That is to say, we may not be able to easily predict and rationalize the beginning of life based on the initial conditions of the earth, because it is likely that it was an improbable fluke. It feels like a lottery winner trying to explain how they won the lottery.
