Implement "Move" ACL or allow moving file/dir just like you allow to rename it when "Delete" ACL is unchecked

Is your feature request related to a problem? Please describe.
Yes. I can not move file/dir to another location when "Delete" ACL is unchecked.

Describe the solution you'd like
I would like to be able to move file/dir - this clearly does not "Delete" the file/dir. Right now you are allowed to "Rename" the file but can not move it. It is strange. Renaming is very similar to move action. Please implement additional "Move" ACL in 'settings/admin/groupfolders' next to "Write Share Delete" checkboxes so they become "Write Share Move Delete".

Describe alternatives you've considered
Allow to move file/dir when "Delete" ACL is unchecked just like you allow to rename it right now. In such case there is no need for new "Move" ACL.

Additional context
Currently if you uncheck "Delete" ACL for group folder then the Desktop Client crashes if you try to move file from one dir to another.

On first sync it prints error:

2021-08-31 03:09:17:461 [ warning nextcloud.sync.networkjob ]:	QNetworkReply::ContentAccessDenied "Server replied \"403 Forbidden\" to \"MOVE https://foo.bar.com/remote.php/dav/files/john.doe/GroupFolders/foo/bar/jhghg.txt\"" QVariant(int, 403)
2021-08-31 03:09:17:461 [ warning nextcloud.sync.credentials.webflow ]:	QNetworkReply::ContentAccessDenied

On second sync try client crashes and closes.

Tested on Desktop Client 3.3.2 Win 10 Pro 21H1.

Actually, you can't rename a file if you're in a group without delete permission - tested with NC 28.0.1 and Group Folders 16.0.3

-> If the considered user is in a group (G1), which got access to the group folder (folder visible and accessible), the user is able to rename files - no ACL active for G1, thus no ACL applied.
If the user is additionally in another group (G1 & G2), which got active ACL (no delete permission for G2), the user can't rename files within the group folder.

I could find issues with people complaining about the old behaviour that one can rename without DELETE privilege and issues with people complaining about the new behaviour where you need DELETE to rename files.

Both are right in their scope. If you rely on given path names for some data, noone should be able to rename stuff. If you have people uploading "new folder" and "unnamed document" frequently, then you'd better enable renaming it.

So I think there is a real need for a RENAME / MOVE privilege separate from the others. Can this be implemented in groupfolders or would this be a change in core?

As they made this change in the core v29->v30 and a lot of folks relied on the behaviour having people to rename files/folder without granting deletion rights it would be great finding a solution for this ASAP. Either in core or at least within this app.
