True, but there can still exist a presumption that a large proportion of those connections aren't meaningful. I have no qualms connecting with a vendor or recruiter I just worked with, even if briefly on a single project, but after 6 years of no contact and 2-3 employers later, that connection isn't going to be useful for something like an introduction, if we even remember each other.
