Yes this documentation is outdated, I introduced this change with this [PR](https://github.com/iTowns/itowns/pull/2060) and was not aware of this documentation. It should be updated with something as you propose except `updatePointCloudSize`...

may be related https://github.com/iTowns/itowns/issues/2074

I rather the single Github repository option for the reasons you said. Theses packages/addons are going to be related each other it would be easier to maintain them if all...

It could also be good as mentioned [here](https://github.com/iTowns/itowns/discussions/2098#discussioncomment-5969085) to let the possibility to the user to not specify the `parentElement` of the widget.
