This the best way forward: a full suite SDK for DApp developments.

Steem should not be used for rewardpool. SMTs with DApps can take care of it. Scot based @steem.leo, @sct, @palnet, @sportstalksocial have already proved it. Moreover, it is simple, for example, there is only LEO token: no LEO backed dollar, no LEO power, even all rewards are paid in 100% liquid LEO. DApps can play with their own reward pool distribution algorithm and find out strategy for own onboarding. Moreover, success will depends the DApp's developments. Investors and creators will move to the appropriate and successful DApp. It will be plethora of DApps, the fittest/best DApp/SMT will come out. Successful SMTs will drive Steem's price too.
