Yeah
See that quote (heh...) I pulled down from the Release notes:
""Quoting other people is not implemented yet, and it is currently not possible to mark your own posts as allowing quotes. However, a new “Who can quote” setting has been added to the “Posting defaults” section of the user settings. This setting allows you to set a default that will be used for new posts made on Mastodon 4.5 and newer, when quote posts will be fully implemented.""
