Just talking about wheel builds:
When I was selecting components for my new rear Vado wheel, I paid special attention to have the rim equipped with eyelets in spoke holes, as these eyelets distribute the stress around the spoke well (the rim is less apt to crack). Only recently, I had a closer look at the front wheel, which was delivered by Specialized on my Vado 5.0 to 6.0 warranty upgrade. Funny to think about it but the new Specialized wheel had spoke hole eyelets too... While the original rim for the front wheel had no eyelets!
