To give one example that is particularly troublesome:

Time Machine allows verification of backups when writing to a network share. When you write to an internal or external drive, you can’t verify your backup.

Any corruption to your backup over time can’t be detected so you can’t really trust that the backup is going to work when you need it.

On one hand, sure, there’s no way to verify historical file changes as the old versions are no longer on the current disk, but I should at least be able to verify that the current snapshot matches my current file system.
