To fuss about the little imperfections on our siding renovation?

[Jona Santiago]

This is our first rodeo to do a big repair like this. Our siding contractor sent me this attached picture of the ongoing project and I noticed those little cracks on some siding boards(near the tan colored corner post). Most of those siding boards came with the sale of the property. The seller stored them in the backyard so they got rained and all that. Are those too little of imperfections I should just ignore them or shall I ask the contractor to fix them? I don't want to be unreasonable (but I paid him $20K for this job:) .  I will really appreciate your advise.
