Just to be clear, they are also updating the "quick-fixes.txt" list which updates every 12 hours: https://github.com/uBlockOrigin/uAssets/commit/886064b7c2014b6345225e3213b585bd7908a553
So it should be a bit quicker than 3 days.
Also there is some advanced settings you can change to make it update out of date lists quicker: https://github.com/gorhill/uBlock/wiki/Advanced-settings#autoUpdateAssetFetchPeriod
Change these three to a lower value to increase the frequency of updates of OOD lists.
