Frage
In SharePoint Online and SharePoint 2019, as part of the Modern Team site, there is a DefaultSPGroupsSiteMaster Web feature with the ID d5a4ed08-27b9-4142-9804-45dec6fda126. This feature does not exist even in SharePoint 2019.
Does anyone know what this feature is supposed to do? I could not find any documentation describing it. I have checked if this feature eixsted as part of a classic Team site and it it's not present there. So I am curious what this does exactly.
This is how I have retrieved this feature:

Lösung
DefaultSPGroupsSiteMaster (e233eb34-e720-4ff9-9f53-a5aabc706d12) is a Hidden feature first introduced in SharePoint Online circa 2018. It was then added to SharePoint 2019 as well.
This feature is very lightweight and only does the following:
- Ensure Visitos, Members and Owners SP Groups are created and contain a group owner.
- Assign permissions to these groups.
- Add a web property
vti_createdassociatedgroups
that contains principal IDs for the SP groups mentioned above.
The feature activation code is located in the Microsoft.SharePoint.dll
(SP 2019 version), in the DefaultSPGroupsSiteMasterFeatureReceiver
class.
