Applying banners to shields and using other things in the offhand. and other misc stuff.

The thing I am saying is as it stands you cant apply banners to shields and your offhand has limited use where as in Java it has the use of acting as a quick means for placing or using the thing in your offhand. Since 1.15 was gonna be about making bedrock correlate better with Java will these functions be seen or considered for the newest release? Its both a Question and technically a bug since banners to shields is a feature I do not see in the expected patch notes for bedrock despite it being a legitimate function in Java. I have not tested other versions besides Window's 10 PC so i do not know if this intentional or not either. I just know its a thing to expect if your trying to improve correlation between the two versions. Also posting this to ask is it even possible? Another thing I notice Is Curse of vanishing will be implemented but not curse of binding so I also ask about that to if there are plans to add it.
