You limit builders by forcing anything they build to hold an alpha/beta/preview label, where it doesn't graduate to having the full backing of the company if maintainers can't fill in the rest of what's necessary for long-term maintenance. The incentives revolve around how many "builder" projects eventually end up losing the alpha/beta/preview label and how long it took to lose the label.
