Incorrect version of USBCore.cpp in package registry?

[apanagar]

I recently installed PlatformIO for development on an Arduino Due. When going through the basic environmental setups, I built and deployed the Blink sketch. During compile, I got the following warnings:

On inspection of USBCore.cpp, I see the following:

however, the latest code in the ArduinoCore-sam repo has the following commits, which seem to be more recent than my screenshot, and also resolves the warning above 790ff2c.

I'm new to PlatformIO and don't quite know my way around, so apologies if I am looking in the wrong place, but it seems to be that this is where the package is installed from https://github.com/platformio/platform-atmelsam/blob/1c15f3aa8595fa707f510221611ee051ab928efa/platform.json#L46, which does appear to be the latest version the repository. Also, here is what I get when list my packages:

My guess is the package registry has older version of the code in it, but I'm not entirely sure how to download the actual package/file/tar.gz described here: https://registry.platformio.org/tools/platformio/framework-arduino-sam/versions
