hey there - yes this is unfortunately the case as we had to fix a bug in the mutable extension, issue 8133 doc'ed at https://docs.sqlalchemy.org/en/14/changelog/changelog_14.html#change-f8b03063d70397a8f275287ed2c8f2e6 . this seemed to be enough of an edge case that I didn't attempt to reconcile the old broken format.
