It currently says:

The hub on this platform. nil if the platform has not had the starter pack applied or hub was destroyed but the platform not yet deleted.

If the hub is destroyed the platform will be deleted at the end of the tick but is otherwise valid to use until that point.

The last line is wrong, as the platform is only deleted if the hub dies. But destroying it is completely fine and is easily done in editor.
The first line is technically correct, but misleading as it implies between starting pack applying and hub dying the hub always exists, which is not true, it can be deleted and created many times in that time. It should probably just say "The hub on this platform, if it exists."

Fixed the docs for the next 2.1 release, thanks for the note.
