This tool is deprecated but at the same time breaking it would be a problem.
Do we really need to make this change?
Go does not remove or stop supporting deprecated methods in the standard library (this would break the Go1 promise), they just discourage new usage versus better designed utilities.

The aim was to remove overhead calls to os.stat since filepath.WalkDir allows us to interact with directory entries directly via os.DirEntry without needing to gather full file metadata (size, permissions, etc) , which avoids the overhead of making an additional system call (os.Stat) for each file.
But if this would break the Go1 promise, Do you want me to close this PR?

This overhead is negligible though, isn't it? This isn't a high performance operation (also this particular codepath is effectively dead unless developing very old kubernetes releases)
But if this would break the Go1 promise, Do you want me to close this PR?
Er no, Go cannot remove the old method, so continuing to use it is safe. Us switching to a different API just requires not introducing our own bugs.

What would you like to be added:
filepath.WalkDir where its appropriate.
Why is this needed:
To reduce unnecessary stat call.
(filepath.WalkDir uses os.DirEntry, which is more lightweight and avoids redundant stat calls, making it faster and more efficient for traversing directories when full metadata is not needed.)
Fixes: #34250
