I expect that to be the case, but releasing incompatible content results in either the former or latter now being bugged.
In the essence it’s not usable in the game due to structure.
Also should not release components of a new system without releasing the foundations of new system. It’s bad in terms of development standards.
(and yes I know technically it exists with the taverns/keepers, but all of the other craftin stations / thralls are still with the previously existing system.)
