The other subtle thing I take issue with on this is: What relationships, exactly? Most of the time I've seen this surface as a few early customers you might not have otherwise gotten, which is great and necessary, but IME that well runs dry pretty quick, and those customers oftentimes don't stick as well as ones that were found on merit. A better relationship with vendors? Again, weird, merit should trump that personal relationship.
If you're building a business that relies on a small number of very high value contracts, I think I could see a world where having a foot in the door on those high value customers is worthy of elevating the body that foot is attached to toward Founder. That isn't, generally, how most software companies sell software though.
