No more manual configuration of CPU/Memory for Windows VM's - what now?

I just read in the release notes for 20.4.0 that this feature has been eliminated. I am one of the users who does set a manual configuration for my Windows VM - I have a program that does use plenty of CPU/memory, so I often assign it 10 CPU's and 64 gb of memory (I have 96 gb of memory on a M3 Max, so that leaves 4 CPU's and 32 gb memory for the Mac side). The recommendation shows 4 CPU's and 8 gb RAM for the Windows VM.
Am I just stuck on 20.3.x, or are there other suggestions for managing my Windows VM?
