Actually, when you think about it, it's quite simple: the most important matter for the Jade Emperor's side over these ten thousand years is to assist the Jade Emperor in attaining the Dao Lord status, with everything hinging on the Jade Emperor.
If the Jade Emperor cannot become a Dao Lord, even if several more True Immortals emerge on the side of the Jade Emperor, it wouldn't affect the grand scheme at all, nor change any shifts in the situation.
In order to ensure the Jade Emperor becomes a Dao Lord, even the resources available to the Jade Emperor's few Princes in the Heavenly Court are limited, and they all remain at the level of Supreme Overlords.
Of course, the expansion plans of the Heavenly Court and the enhancement of the Divine Continent World's foundations are not without benefits to all beings. As the Divine Continent World continuously improves, the cultivation environment changes and the longevity of cultivators increases accordingly.
