I think recurring support contracts or subscriptions are actually very problematic in the case because the gains will naturally go the projects highest up the dependency tree because they are the most visible. However, if we payed for change requests in individual projects there would be the possibility for 1. money to trickle down from well sponsored projects to their dependencies when those higher level projects need changes 2. teams to spread money around by directly requesting changes to more obscure projects they depend on.
