Yes, that's always good to check but given the size of the repository (the number of directory and files is just massive!) it can be really annoying to navigate. Often faster to just run the winget CLI somewhere.
winget.run should add a link to the manifest directory, that would be useful.
For future reference the GitHub manifest page seems to be the better choice:
