Eric,

1. If you are not changing CretePopUp, your proposal does not really solve my 
problem.
It means my proposal still has merit.
Do you have problem with moving CreatePopUp implementation into a new library 
class?
Once again, the function will stay in UefiLib, but the implementation will be 
changed to call a new function UiCreatePopUp
from the new library class UiLib.

2. In my opinion, adding HiiGetUserSelection to HiiLib is a bad idea because it 
will create the same problem as with CretePopUp.
The rest of HiiLib is generic. It operates within the scope of HII database 
definitions from UEFI specification.
The new HiiGetUserSelection you are proposing deals with presentation, which 
means it is may get changed to match project UI.
HiiGetUserSelection can be added to the same new UiLib that I'm proposing.

[[Eric]] I plan to add this API to HiiLib which existed at 
MdeModulePkg/Library/UefiHiiLib. I think it's belong to HII scope.

[[Eric]] I plan to not change it. Just suggest user to use new API and 
deprecated it later.
