Question:
I’ve recently brought up with some that the GetVariable##() functions in UefiLib are probably incorrect as they are written (because they assume things like gRT and gBS availability). Would it perhaps make sense to move this interface up into the MdePkg scope and leverage it to start removing some of those assumptions?
I already have a TODO to start splitting UefiLib along phase lines (PEI, DXE, MM, etc), but that work could largely be obviated with this abstraction.

That sounds very reasonable to me. I have done something similar with basic PPI/Protocol services to abstract phase specific differences that a lot of code simply doesn't need to care about. I even like the idea of a general "phase agnostic services library" that handles these kinds of things that would suffice for a lot of code that doesn't need driver model complexities or some other phase specific complexities. That would likely be more an RFC discussion though. I think case by case is also fine and more aligned with the current library design.
Regards,
Isaac

Subject: [edk2-devel][edk2-platforms][PATCH V1 1/1] MinPlatformPkg/Variable*Lib: Build VariableRead and VariableWrite libs
Add the VariableReadLib and VariableWriteLib instances to Components to ensure build when building MinPlatformPkg.dsc.
Add a NULL library instance that provides the non-functional library instance for VariableReadLib designed for all phase use.
