The advantage of including everything, or the problem with trying to cherry-pick, is that many problems are only the result of the partial but incomplete sets of interoperating components.

If service A is always trying to use service B, but you removed service B, you can have annoying problems caused by service A hanging and timing out behind the scenes or presenting buttons that don't work etc.

One way to avoid that is never remove anything, but another way is to remove both A and B.

One way to get both A and B without knowing what they are, is get everything.

And this particular method, using an actually fairly managed and graceful command (managed/graceful meaning not just removing files and editing the registry, but only running a user-facing command and interface) is like an automatic filter to include only things that don't actually break the OS.
