Within new yearly release of OAS (2023 or 7.0) features, which are in OAC in Preview mode:
Semantic Modeler
Excel Export
Generic REST Connector
are not included. As we learned the reason is, that in OAC those features are updated in 2 months cycles, which would not be possible for OAS.
But generally, this is something we could live with - simply saying is better to have something (just for exploration/testing purposes, not for production usage - admin still have the option to turn in on/off on particular environment in Console) then nothing. This is especially the case for Semantic Modeler, where having the chance to "touch it" and play with it (and provide then feedback to Product Mgmt, what we are missing in Semantic Modeler and have a chance to "influence" direction, where Semantic Modeler is heading) would be really very useful (then waiting for "final version").
So, pls, consider this for OAS.
