Value Plan is moving towards a portion of this. However, it requires two things:

1. The individuals who carried out initiatives were financially compensated at a fair level (they are all volunteers who make nothing)
2. On-chain fair competition could be established (no voting based on how much someone is liked but an automated process that only considers metrics)
   While Value Plan through its dashboards, processes and tools can create 2., it can't do anything about 1. Nothing can be done about compensating anyone except for designers and developers in part because they work on call, meaning they can't take regular jobs on during that time. Everyone else is a volunteer.
   There is nothing that says other projects can't be funded and there's even a Plug-In Proposal system for that where someone wants to go that route but not handle the funds.
   The initiatives are lumped together because they work together. No initiative exists that isn't used to make other initiatives and results more viable. Standalone activities don't make it past the idea stage.
