Making NEW process feel like the OLD one

With most Microsoft products, you can usually make NEW versions feel and work like the OLD ones as you make the transition.  But this new Microsoft Purview seems to do away with a lot of the functionality of the "Classic eDiscovery" process.  Are there any ways to get things back, such as:

• Larger PST file size limits?  Mine appear to be stuck at 10GB now
• De-duplication.  This appears to be gone.
• Extract all results into a single folder.  This appears to be gone
• Do allow the search to look for Teams, Sharepoint and OneDrive results even if i opt not to extract them?
