So I wanted to know that If I keep them invalid what problem they can cause?

Steps I took to know myself:-

I have searched over Oracle support and google by object name but the only thing i get there is patch no to resolve the issue or in some case that ignore these objects they will do nothing.

If anyone have information about these object and what problem they can cause in application. Please do share.

Thanks in Advance!!!
