There are also several places internally that rely on _readyPromise to ensure backwards compatibility during the deprecation process. These all have comments that call out the removal of readyPromise.

I just noticed that there are hundreds of "deprecation warnings" relating to this issue that are somewhat confusing. eg

createWorldTerrain was deprecated in CesiumJS 1.104.  It will be in CesiumJS 1.107.  Use createWorldTerrainAsync instead.

Note that the word "removed" is missing... I count 317 of them. But there are also quite a few with the correct message.

Thanks @markw65, the deprecation warnings have been updated in #11311 to include the missing word. It should make it into the 1.106 release.
