HI all,

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2298
In the MdePkg, there are two folder for the DevicePathLib:

1.       MdePkg\Library\UefiDevicePathLib

2.       MdePkg\Library\UefiDevicePathLibDevicePathProtocol

UefiDevicePathLibDevicePathProtocol is created to use the protocol to reduce the driver size which consume the DevicePathLib.
But it has duplicate code with #1. So I want to merge these two folder into one. But many platform implementations consume #2.
If we merge #2 into #1, there might be a lot of platform changes for both close source and open source.
Can anyone give me some suggestions about this? Do we have a progress to retire some implementation in the edk2 repor?

There is another question about MdePkg\Library\UefiDevicePathLib\UefiDevicePathLibOptionalDevicePathProtocol.inf.
This one implements the interface to choose the protocol first, then change to local implementation if no protocol is available.
It requires a fix and it is already sent to the community. But what's the purpose?
Local implementation, i.e. MdePkg\Library\UefiDevicePathLib\ UefiDevicePathLib.inf, can make sure its usable. And it can't reduce the driver size. If it is useless, can we directly remove it?

Thanks,
Zhichao
