Confusing federated share options

[T0mWz]

When I create a federated share, I got now two options.
Why should I choose for Federated Group ?

In Owncloud core we have multiple share types like user, group, link, ...
federated was handled as a remote user and there was no implementation for the remote group by default.

so we decided to create a federated group option to handle remote group sharing with minimum change inside de core.
there is the same share type in Nextcloud also.

Additionally in Owncloud, you can have a user and group with the same name and Owncloud does not query the result from a remote server to find out if there is any real [email protected] and it shows the result from its own.

so, two separate options are shown to enable the user to share a file with a remote user or a remote group.
when you click on the first option federated you are asking the remote server to share this file with john.doe@example user.
but the second option means that you want to share the file with john.doe@example group
