UEFI-based screen capture tools

I notice that Microsoft’s Project Mu has a PrintScreenLogger tool (Ctrl+PrtScn):

https://microsoft.github.io/mu/dyn/mu_plus/MsGraphicsPkg/PrintScreenLogger/Readme/#printscreenlogger-operation

and that it is already getting some forks:

Before that, there was RU.EFI command line tool (F12):

RU.EFI updated, screen snapshot support

and Nikolaj’s CrScreenShotDXE (LeftCtrl+LeftAlt+F12):

screenshot-taking UEFI DXE driver

And there are probably a few other options I’m not aware of, including by IBVs/ODMs.
